Right now you can get a FREE song from Buy.com but you have to do this before 5/17/2006. There is no catch or gimmicks and all you have to do is click the link below to redeem your coupon. Once you have redeemed it you can go ahead and select your song from their music store. When you go to complete the checkout you will notice that the coupon has been added to your cart.
You may, however, have to pay for sales tax because the coupon is only valued at $0.99. It is still a great deal.
