I just heard about website on another forum, its still in its Beta stage right now. lala.com is a CD swapping service.
*Member's compile a list of CDs they will trade for new music
*Members compile a list of CDs they want
*Members then use a searchengine to find a match for swapping CDs
*LALA provides postage paid mailing envelopes ($1/trade according to website)
*20% of LALA fees gets paid to musicians. (2nd hand record stores do not pay any musician fees).
The website is still in its BETA, and is currently "invitation only" (presumably until all their software glitches are worked out), but you can send them your email and they'll add you as soon as they can.
I've already tried to sign up, I've got nothing to lose but some CDs I don't listen to anymore!
