Jamendo, a music site with over 10,000 CC-licensed albums, has teamed up with MP3tunes:

Give it a try at www.mp3tunes.com/jamendo – you’ll find 10 exclusive playlists of the best in rock, hip hop, jazz and more from Jamendo. Sign up for a Music Locker – it’s free to try – and then with a single click get each playlist you like added to your to your collection. You can also add personal music from your computer in your Locker with free, easy-to-use software.

This is very cool. Heavily curated playlists are one way to address the discovery problem. Using freely licensed music is how internet music startups can get the economics of all other internet startups. Unsaid in the announcement linked above, all of the playlisted tracks in the Jamendo/MP3tunes collaboration are licensed under CC BY-SA, allowing commercial use and recalling a recently posted quote from Lucas Gonze on commercial use and “empowering businesses to build support systems for your music.”
