I'm not sure if this is already known, but this site is loaded with samples and loops under a creative commons agreement with those who upload. There is a warning that they cannot be 100% sure that everything is copyright free, so use at your own risk.
I've been sampling some loops and stuff directly from the site into the SP for fun. I use the audio out on my ipad, connected to the SP, and just sample in real time from the site when I find one I like.
EDIT: added the link!
