If you're going to get PoW, get the PC or Xbox version. The PS2 version not
only doesn't have the DirectMusic (obviously) but it's got some nasty bugs

Thanks very much, Ciaran! Just what I was hoping to hear. :-) Thanks again.

By the way, I still haven't heard the music you did for PoW. I guess I'll go
and buy the game, just to check out the music. If I do, it had *better* be
good!! ;-) Just kidding.
