Does anyone know how to restore a playlist of tunes I manually made in Music App (Monterey 12.5)(19,1 iMac)

Somehow I deleted it when I picked up my keyboard. What file stores the playlist data?

If you didn't close the Music app yet, you can undo it from the Edit menu.

Oops, too late. Thanks anyways.

One file must change when I make a new playlist, in order to be retained. The modified date will show. But where to look? There used to be an app that would show the latest files changed on a disk. Is there an app for Monterey that’s similar?
