Yeah, that's it. When I deleted it before, I thought it was still seeing deleted files,
but now I think it must be finding all the sound files in KDE.
Really would be most helpful to use the file name in the case of no tags.

Searching is really useful, you can isolate an album.
Doesn't work for my repeat track needs, though.
I have a bunch of tones. I need to be able to select one,
and then have it play over and over until I select another one.
I use this technique to identify feedback frequencies in sound systems.

YouAmp's interface is perfect for it.
Nice big finger-friendly buttons, a good scroller, and volume slider on screen.
Just needs repeat track.
