This year, Zune is a title sponsor at CMJ - and for us, it's all about music discovery. So what does that mean? It means we're presenting music showcases with some top artists, working with some top music blogs to get awesome coverage, and putting together some amazing playlists that celebrate the best music to come out of CMJ.

Over its 20 year history, CMJ has been instrumental in launching the careers of bands like Arcade Fire, The Hold Steady, Mars Volta,  Modest Mouse, The Yeah Yeah Yeahs, My Chemical Romance, Hot Ht Heat, Justice, MIA, Band of Horses, and many more. To celebrate CMJ's venerated history, the Zune team spent hours upon hours putting together a 100-track playlist: CMJ Rewind. And if you can't get enough of CMJ music, check out the CMJ Collection playlist: 250 tracks from bands playing this year.

Not to let the rest of the Zune org have all the fun, I made a playlist too! Check out Zuneinsider CMJ 08
