Beets is the media library management system for obsessive music geeks, an infinitely flexible automatic metadata corrector and file renamer, and a batch audio file transcoder. Beets is a simple music metadata inspection and modification tool for tons of audio file types, and an MPD-compatible music player. 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. Then it provides a bouquet of tools for manipulating and accessing your music. Because beets are designed as a library, they can do almost anything you can imagine for your music collection. Via plugins, beets become a panacea. Fetch or calculate all the metadata you could possibly need: album art, lyrics, genres, tempos, ReplayGain levels, or acoustic fingerprints. Get metadata from MusicBrainz, Discogs, or Beatport. Or guess metadata using songs’ filenames or their acoustic fingerprints.

Music Tag is a Windows and macOS application that helps users organise and complete their digital music collections by downloading missing metadata and artwork directly into the music files. Using advanced digital fingerprinting technology and a database of over 35 million songs, Music Tag automatically finds accurate information such as title, artist, album, track number, and cover art, then updates audio files so they display correctly in music library managers like iTunes, Apple Music, Windows Media Player, and portable devices. The app also lets users manually add, edit, or remove tags and supports common formats including MP3, MP4/AAC, WMA, and FLAC. The free trial lets you try all manual features as well as download information and artwork for your tracks. It is limited to saving changes to a single track per run. Purchasing a license removes the limitations to enable full tagging capabilities across all files.
