you listen to what you like. others will, too
it's a business card theory. you make a cd of your favorite songs, a virtual musical representation of you. someone reciprocates. you trade. it's a win-win situation, no wasted cd or wasted money. bartering rules.
once implemented, this site will serve as a list of those who have cds available, and related information, allowing people to connect with people. ideally a repertoire would form, effectively germinating musical tastes faster than any sort of musical movement or pseudo-song-shout out.
watch for cool things to come....
