I haven't looked at YouAmp in a while. You've made good progress.

Took me a little while to get Preferences|Music Folder|Other working.
First I didn't realize that you need to doubleclick on the desired directory and hit Open,
or it reverts to the entire card.
Then it takes a program restart to get it to update the database,
and hitting Browse to make the cleaned database apparent.
Got it now, though, and it all works.

Albums play alphabetically. Is there a way to play in track order?
