Also, when I compose a playlist on the Palm and beam it to the empeg, it inserts the files rather than creating a new playlist - is this intentional? Can this be changed somehow?

This is the way it's supposed to work. Creating a new playlist on the Empeg would be a little more complicated, I'd have to write to the Player DB and do a bit more than I've focused on for this project. My intention was to satisfy passengers and myself when they ask me "What songs do you have?" and also "Can you play this, then this, then this". Just an easier way to browse and insert songs than using the front buttons (I've screwed up my playlists many times by replacing, not inserting songs).

Later I'll modify it so you can insert/append/replace/enqueue, but I probably won't work on creating a new playlist that will be avialable in the menus.
