Soundiiz imports your playlists and favourites easily from Discogs to Last.fm
Discogs is a website and crowdsourced database of information about audio recordings, including commercial releases, promotional releases, and bootleg or off-label releases.
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.
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.
