「
Welcome to the Last.fm dataset, the official song tag and song similarity dataset of the Million Song Dataset.

The MSD team is proud to partner with Last.fm in order to bring you the largest research collection of song-level tags and precomputed song-level similarity. All the data is associated with MSD tracks, which makes it easy to link it to other MSD resources: audio features, artist data, lyrics, etc.
