Actually it is there. I finally found it. If you click on the song name in the Now Playing screen, and from the menu that comes up choose "Show Track Info" it's there. I'm happy! Thanks again for the theme!

(I still wish there was a player that could show the file type and bit rate on the Now Playing screen, but I'll live. As far as I know Rock box is the only player on Maemo that can give you this information at all.)
