You'll find thousands of royalty free music tracks at this site: http://www.Sounddogs.com/

Great quality and selection. I have found that most composers there have long Hollywood feature film and major productions credits.

Hope it helps

I think you can try opuzz.com if you want a pack or something like digital juice as they are one of the few that have their whole library on hard drive. plus they having a sale now. I think the other is oohh I just can't remember the name.
If you want free music try jewelbeat.com or incompetec.com

You should try Xylote.com for royalty free music. You can find a nice collection of soundtracks and music loops.
