Beets is a media library management system for obsessive-compulsive music geeks.

The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. It then provides a set of tools for manipulating and accessing your music.

Beets also includes a music player that implements the MPD protocol, so you can play music in your beets library using any MPD client.
