TuneRight

TuneRight recognizes untagged and mislabeled songs by listening to them, then finds the matching release, so the details come from the right album.

See the proposed title, artist, album and cover beside each song. Apply what looks right, pick another release from the song's menu, or skip it.

Songs from the same album are grouped together, so you can check a release as a whole and apply it in one go, while still changing any single track.

Album art comes from fanart.tv, with Cover Art Archive filling the gaps. A missing genre can be filled from Apple's music store, and you can always choose your own.

Prefer to type it yourself? Edit Tags puts the title, artist, album, year, genre and cover in one place, with a final look before anything is saved.

Every applied change can be undone, even after you quit TuneRight, because the undo history stays on your Mac.
