I can't seem to work either of them out.

For lyrics Im using with "Lyrics Show" inside "Dockable Panels". The only thing that sucks is that if I hover the cursor over the lyrics foobar loses focus... that really bothers me.
For stats, remember you need to have your library scanned somewhere in preferences dialogs (it won't work with tracks not in the library... or maybe that's just an option I activated).
