Get on this before it gets shut down

If you can't use existing P2P networks for whatever reason (like if they're blocked or if you've given in to RIAA scare tactics), this is a good site. It's useful if you just want to sample an artist before you buy, because the bitrates are fairly low (radio-quality). It's pretty funny, too--most of the files you d/l are .rbs files (whatever the crap those are) and you have to change the extension to .mp3 to make them work. I assume it's their way of staying under the radar, for a while at least. Even so, I suspect it'll be shut down before too long.
