Messy tags across a whole folder? One pass, done.
Messy filenames, empty titles, keys written five different ways? Fix tags, cover art, and filenames in bulk, even for folders you never added to the app. Always preview before you save. Included in Premium.
Messy filenames like “track_final (1).mp3”, empty titles, keys written every which way. Fixing them one by one takes hours.
Edit many tracks at once
Select a batch and edit once. Fields you do not touch stay as they are.
Build your own action groups
Drag Camelot, BPM, and the filename into slots and see the result on a real track right away. Save it as a group to reuse.
Rename files from tags
For example “8A - 128 - Track name.mp3”. Split filenames back into tags too.
Write key and BPM
Put the analyzed key and BPM into tags, the title, or the filename.
Cover art

Never overwrites
Always a preview first. Existing files are never overwritten.

FAQ
Does editing tags lose labels or analysis?
No. Labels and analysis results stay as they are.

No. The old key at the start of the title, comment, or filename is replaced.
Can I edit folders outside the app?
Yes. The Tags tab opens any folder on your computer.
