I case you know what I can do to debug it pls let me know…
Wow, everything looks right.
Might help to put your debuglevel to 9 and see what that tells you. It should show you the actual command it’s running to play that song.
Also, connect with iTunes and verify that the .ogg files show good metadata (title, artist, etc) and that when you do a “get info” on a song, it shows it to be a .wav file.
