And streaming has amplified its presence. Since the 2000s, millions of songs have appeared online, becoming listenable and shareable. And millions of data have been made available. Information on albums, tracklists, discographies, concerts, videos\u2014so much so that it&#8217;s dizzying. <strong>But where to store this data? Where to find this information?<\/strong><\/p>\n\n\n\n<p>In a world where everything moves very fast and information is scattered, it&#8217;s essential to have a platform that centralizes everything. <strong>And that is constantly updated, collecting everything that can be collected<\/strong>. Then, to make it available to everyone as an open source platform.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/featured_image_musicbrainz-1024x512.png\" alt=\"The biggest music databases and the finest recommendations\" class=\"wp-image-6154\" srcset=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/featured_image_musicbrainz-1024x512.png 1024w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/featured_image_musicbrainz-300x150.png 300w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/featured_image_musicbrainz-768x384.png 768w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/featured_image_musicbrainz.png 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Let&#8217;s just say the name, MusicBrainz, is quite fitting. It is literally a gigantic brain that summarizes everything you want to know about your favorite albums, songwriters, and so on. Where you can access everything related to music, including artists, labels, etc.<\/p>\n\n\n\n<p>And it&#8217;s been around for 25 years! In 25 years, you can imagine that MusicBrainz has had time to amass an incredible amount of data, <strong>which is now accessible in just a few clicks<\/strong>. For example, you simply enter an artist&#8217;s name in the MusicBrainz website&#8217;s search bar to access all the existing information about them.<\/p>\n\n\n\n<p><strong>This provides access to sourced, reliable, and accurate information<\/strong>. In an increasingly digital world, data must be archived and shared. It is especially true in the music industry, where the physical market has declined significantly in favor of digital.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-from-physical-to-digital\"><em>From physical to digital<\/em><\/h3>\n\n\n\n<p>In this context, it&#8217;s difficult to read credits, liner notes, and other information that were previously available on CDs or vinyl records. <a href=\"https:\/\/soundiiz.com\/musicbrainz\" target=\"_blank\" rel=\"noreferrer noopener\">MusicBrainz<\/a> aims to fill these gaps. Thanks to carefully selected contributors tasked with verifying information and rights, <strong>MusicBrainz functions much like Wikipedia, putting up barriers to protect the sources and information made available.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/maxresdefault-1024x576.jpg\" alt=\"The biggest music databases and the finest recommendations\" class=\"wp-image-6160\" srcset=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/maxresdefault-1024x576.jpg 1024w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/maxresdefault-300x169.jpg 300w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/maxresdefault-768x432.jpg 768w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/maxresdefault.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Many users utilize MusicBrainz to catalog the music they own at home, for example, on physical formats. This gives them access, in black and white, to their music catalog, which they can browse at their leisure. Because it operates independently of a streaming platform, where info is hard to find, especially when it comes to producer credits, mixing engineers, etc, the data in MusicBrainz is generally less extensive and easier to read.<\/p>\n\n\n\n<p>It&#8217;s also a way to blend digital and physical media while retaining the numerous advantages of online storage. In 2012, MusicBrainz forged a partnership with the Internet Archive for image uploading and storage. And two years ago, another initiative in collaboration with the Internet Archive launched: Event Art Archive. <strong>This project is dedicated to archiving artwork related to events, such as festivals or concerts.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-non-profit\"><em>Non-profit<\/em><\/h3>\n\n\n\n<p>Note that <a href=\"https:\/\/metabrainz.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">MetaBrainz<\/a>, a non-profit organization, owns MusicBrainz. It means that MusicBrainz has no commercial objectives and is not affiliated with any structure (e.g., a label, streaming platform, or other). <strong>This 100% independent operation allows for transparency and freedom in the information collected<\/strong>, ensuring it is not biased toward any artist or label.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"717\" height=\"341\" src=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/Capture-decran-2026-05-06-165617.png\" alt=\"The biggest music databases and the finest recommendations\" class=\"wp-image-6161\" srcset=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/Capture-decran-2026-05-06-165617.png 717w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/Capture-decran-2026-05-06-165617-300x143.png 300w\" sizes=\"(max-width: 717px) 100vw, 717px\" \/><\/figure>\n\n\n\n<p>At Soundiiz, we are also committed to making music accessible to as many people as possible, and above all, to ensuring it is accessible under the right conditions. <strong>We share with MusicBrainz a passion for music and a commitment to protecting artists and their associated data<\/strong>. It was therefore perfectly logical for us to make our tools compatible and connectable!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-biggest-music-databases-and-the-finest-recommendation-systems-listenbrainz\"><em>The biggest music databases and the finest recommendation systems &#8211; <strong>ListenBrainz<\/strong><\/em><\/h2>\n\n\n\n<p>Are you familiar with Last.fm? <strong>This tool, used worldwide, lets you view the history of the songs you listen to throughout the day.<\/strong><\/p>\n\n\n\n<p><a href=\"https:\/\/listenbrainz.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">ListenBrainz<\/a> works similarly. It&#8217;s called a &#8220;scrobbler&#8221;: an application that runs in the background on your computer and collects data about what you listen to, whether it&#8217;s a media player or a streaming platform. It stores this data in a database, without sharing it with anyone but you. 100% private, unless you decide otherwise.<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/soundiiz.com\/listenbrainz\" target=\"_blank\" rel=\"noreferrer noopener\">ListenBrainz<\/a> can then show you, in black and white, what you listened to most over a week, a month, or a year<\/strong>. It&#8217;s a bit like the recaps different streaming platforms publish at various times of the year, but more comprehensive and easier to access.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"689\" src=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/LinerNotes-Playful_DelightfulMoments_FTRHeader-e1697724347588-1089x733-1-1024x689.jpg\" alt=\"\" class=\"wp-image-6162\" srcset=\"https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/LinerNotes-Playful_DelightfulMoments_FTRHeader-e1697724347588-1089x733-1-1024x689.jpg 1024w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/LinerNotes-Playful_DelightfulMoments_FTRHeader-e1697724347588-1089x733-1-300x202.jpg 300w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/LinerNotes-Playful_DelightfulMoments_FTRHeader-e1697724347588-1089x733-1-768x517.jpg 768w, https:\/\/soundiiz.com\/blog\/wp-content\/uploads\/2026\/05\/LinerNotes-Playful_DelightfulMoments_FTRHeader-e1697724347588-1089x733-1.jpg 1089w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-precise-and-independent\"><em>Precise and independent<\/em><\/h3>\n\n\n\n<p>ListenBrainz doesn&#8217;t just work with streaming services; <strong>it works with everything you use to listen to music online<\/strong>. The usefulness of ListenBrainz became even more apparent when Last.fm was sold to CBS Corporation in 2007 for several hundred million dollars. Rumors surfaced that CBS intended to discontinue Last.fm&#8217;s &#8220;scrobbler&#8221; feature, leaving the community worried about future developments.<\/p>\n\n\n\n<p>ListenBrainz is a listening aggregator and a platform that generates recommendations based on your listening history. Many music enthusiasts use ListenBrainz to discover new artists and albums rather than the streaming platform&#8217;s algorithms. Backed by the MusicBrainz database, ListenBrainz can benefit from an unlimited source of songs to tailor their recommandations. And like MusicBrainz, it operates independently of record labels and streaming services.<\/p>\n\n\n\n<p>It will take a few days of using ListenBrainz for the recommendations to become as accurate as possible. Still, once that&#8217;s done, and <strong>once your listening history is substantial enough, you&#8217;ll find the tool remarkably effective.<\/strong><\/p>\n\n\n\n<p>It acts as a perfect complement to streaming platforms. <strong>The recommendations are different and can then be manipulated via Soundiiz, exported, and shared in minutes.<\/strong><\/p>\n\n\n\n<p>We&#8217;ll explain how below!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-biggest-music-databases-and-the-finest-recommendation-systems-how-to-connect-them\"><em><strong>The biggest music databases and the finest recommendation systems: <\/strong>How to connect them?<\/em><\/h2>\n\n\n\n<p>You&#8217;re starting to get to know us: <strong>Soundiiz is committed to making its services compatible with all available tools.<\/strong> And for several months, we&#8217;ve been working on compatibility between Soundiiz, MusicBrainz, and ListenBrainz. It&#8217;s now a reality!<\/p>\n\n\n\n<p>Many people use MusicBrainz to re-encode their music catalog, which they often own on CD, cassette, or vinyl. The problem: this data is stored only in their MusicBrainz account and cannot be exported. <strong>Many music lovers would like to be able to listen to the tracks they also listen to at home on their turntable or CD player<\/strong> digitally on <a href=\"https:\/\/soundiiz.com\/spotify\" target=\"_blank\" rel=\"noreferrer noopener\">Spotify<\/a>, <a href=\"https:\/\/soundiiz.com\/deezer\" target=\"_blank\" rel=\"noreferrer noopener\">Deezer<\/a>, <a href=\"https:\/\/soundiiz.com\/apple-music\" target=\"_blank\" rel=\"noreferrer noopener\">Apple Music<\/a>, <a href=\"https:\/\/soundiiz.com\/tidal\" target=\"_blank\" rel=\"noreferrer noopener\">TIDAL<\/a>, <a href=\"https:\/\/soundiiz.com\/qobuz\" target=\"_blank\" rel=\"noreferrer noopener\">Qobuz<\/a>, or other platforms.
