I tried it. The concept is good, and the price is right, but only the discs are traded. La-La does not cover the added cost of postage for artwork. You have to trust that the sender of the disc will include the artwork from the jewel case, otherwise you're out of luck. I sent the artwork with the discs I traded, but I recieved no artwork with the couple CDs I received.
Gave up on it.
