The same tags, song after song.
One ‘Feat’ away from a rejection.
Capitals, a leftover ‘FINAL v3’, ‘(Explicit)’ in the title, a print-colored cover. Stores refuse the small things.

Drop it. It comes out ready.
It remembers your artist name.
Tell it once.
Every song after that already has it.
It fixes what a store would refuse.
Title case, guest artists in their own field, the explicit flag, a print cover turned into screen colors, a title from the file name. All with Undo.
Credits on every track in one click.
Add writers, producers or a genre to one song, then use them on all 13.
Your sound stays exactly as it was.
Stamps writes the tags into your files where they are.
No re-encoding, no copies, nothing uploaded.
13 files · tags written · audio unchanged
“Every tag editor I tried looked twenty years old. So I made a sexy-looking app for the most boring job in music.”
Kai Williams, artist, maker of Clips and DOT

Before you download.
Does it change my audio?
No. It only writes tags. Your sound stays exactly as it was.
Which files?
WAV, AIFF, FLAC, MP3 and M4A. Stamps edits the metadata inside each one.
Do stores read these tags?
Distributors take your details from their own forms. The tags travel with your files: promo copies, DJs, Bandcamp, your own library.
What does it fix?
Title case, guest artists in their own field, the explicit flag, a print cover turned into screen colors, a title from the file name. All with Undo.
Can I change the tags later?
Yes. Drop the files again: Stamps reads what’s in them, and you save again.
Is it a subscription?
Never. $29 once, and your first single, EP or album is free.
Tag it right. Then release it.
