Music, Sound, Animation & Image auditioning app

Thanks @nanobot567 !

There's only ever one file playing at a time here, but lots in the list.
List populated with listFiles
On my device I have ~50 files (2xMP3, 1xPDA, 3xPDI, the rest PDT)
fileplayer.new is called on press of the A button.

Do I need to discard the fileplayer after use? I don't think I am doing that right now.
