Replace Last.fm playlist tracks automatically on a Discogs playlist
Using a music recommender system called Audioscrobbler, Last.fm builds a detailed profile of each user's musical taste by recording details of the tracks the user listens to.
Discogs is a website and crowdsourced database of information about audio recordings, including commercial releases, promotional releases, and bootleg or off-label releases.
Soundiiz is the most complete online tool to manage your music library between multiple services. It offers a simple way to import and export playlists and favorites tracks, artists, and albums.
