This API provides a way to fetch or calculate all the metadata for album art, lyrics, genres, tempos and more. This includes metadata from MusicBrainz, Discogs, and Beatport. It also allows you to guess metadata using songs filenames or their acoustic fingerprints, transcode audio to any format, check your library for duplicate tracks and albums or for albums that are missing tracks, clean up tags left behind by other tools, analyze music files metadata from the command line and embed/extract album art from files metadata. Browse your music library graphically through a Web browser and play it in any browser that supports HTML5 Audio. Listen to your library with a music player that speaks the MPD protocol and works with a staggering variety of interfaces. Beets is the media library management system for obsessive-compulsive music geeks.
