THIS IS YOUR MUSIC, THIS IS YOUR MUSIC ON WEED.
OR, THE AMWAY METHOD OF INTERNET DISTRIBUTION
WEED is an internet distribution service that allows users 3 free listens to WEED encoded songs before asking the listener to purchase the song. Once purchased, 50% goes to the artist, AND ... "If you buy a Weed file and share it with someone else who buys it, you receive 20% of the purchase price as a payment for helping to distribute the file. The person who shared the file with you also gets 10%, and person who shared the file with that person gets 5%." via Mi2n.
I like this idea, b/c it gives music consumers an incentive to pay for the music they download.
