Nice.

How do I remove a song from the database, or delete the database?
I had a bunch of mono files it didn't like. It wouldn't play them or read their IDs.
I re-encoded them, but they're still in the list.
I deleted home/user/.musicdb, but YouAmp recreated it, with the missing files.

My application is kind of special purpose, but this looks great.
I would love to see a "repeat one track" function.
