With LimeWire you can have a look at explicitely legal files:
Just select "audio" and as license: "creative commons" and search.
Then just select a file which shows the "cc" icon, rightclick it and select "show license".
In the PopUp-Window just click "Verify", and LimeWire will check if the license is valid (there's quite a few fakes out there, but you can recognize them in the way I described here).
Also you can join the Polar Skulk, whose mission is to push more free and legal files into the Gnutella Network:
