From the site:
jamendo"jamendo is a new model for artists to promote, publish, and be paid for their music.
On jamendo, the artists distribute their music under Creative Commons licenses. In a nutshell, they allow you to download, remix and share their music freely. It's a "Some rights reserved" agreement, perfectly suited for the new century.
These new rules allow jamendo to use the powerful new means of digital distribution like Peer-to-Peer networks such as BitTorrent or eMule to legally distribute albums at near-zero cost.
jamendo users can discover and share albums, but also review them or start a discussion on the forums. Albums are democratically rated based on the visitors’ reviews. If they fancy an artist they can support him by making a donation."
