There's a couple of very talented guys over at MacIdol - there's a lot actually, but these two stand out at the moment. Kilroy de Geek. Check out his "Idea Hamster (My Muse)" Very catchy. and James Bachman. Check out his "Safe inside your house" If one of these guys gets heard by the right people, you will be looking at your first GarageBand created Top 40 song. I can't guarantee these guys will be to your tastes, but at least you will be able to say you heard them before they were famous.
