Lala

.. As a lala member, you can trade the CDs you have for music you really want. Trading CDs through lala is easy. Registering for lala is FREE! You can browse member collections and playlists, search for specific artists and albums, or sample lala recommendations. There are no upfront commitments. Once you decide to start trading, you only pay for CDs received from your Want List. There are no hidden costs or monthly fees. Every CD you receive costs only $1 plus a standard shipping charge of $0.75. The number of CDs you receive will depend on how many CDs you ship to other members. You're NEVER obligated to ship CDs in your Have List. When someone requests one of your CDs, you decide if and when to ship the CD. The more you ship, the more you get.
