Same here. It's happened on every GB ROM I've tried. Hopefully someone can shed some light on this.
Is your music cutting out for a few seconds and then resuming?
Any time I begin music playback and then open any other app, my music force closes. Unfortunately, this appears to be a memory issue. The reason that gingerbread was not officially released for the droid is because the device lacks the memory to be able to run the rom without issues like this.
I've yet to find a gingerbread rom that I don't have this problem with. Guess I'll be switching back to 2.5.
