Yate 10.1.0

If you care how every file in your collection is tagged, you want to decide each field yourself. Yate is a music tag editor for Mac built for that kind of control. It runs on its own tagging library.

• One app for nearly every format you'll run into: MP3 (and MP2), M4A and MP4 with AAC or ALAC, M4B, M4V, FLAC, AIFF, WAV, APE, WavPack, DFF, DSF, and single stream Vorbis or Opus OGG.
• Actions are Yate's scripting system. Build your own tagging steps once and use them again on the next batch.
• Tag data comes from MusicBrainz, Discogs, Beatport and last.fm, so you're not typing album details by hand.
• AcousticID and AcousticBrainz are supported too, which gives you more sources to check a release against.
• Video files get their info from The Movie Database (TMDb).
• Works with your iTunes, Music and TV libraries.

Plenty of other integrations are available through actions.
