The New Sounds of MusicIn this issue, we look at the innovations and emerging business models in the music industry. A note from Editor-in-Chief Amy Cosper.

Music is more than entertainment. It's more than lip syncing your way to the office, or making your air guitar gently weep while listening to Linkin Park. Music is business--and an extremely provocative business at that. Billions and billions of dollars are pumped into the industry every year by enthusiastic, passionate fans. Whether it's streaming through iTunes, Pandora orRdioor spinning on old-school vinyl, music means money.

Music provides the background for everything we experience. It surrounds us as we drive, entertains us when we run, streams to our computers as we rock a spreadsheet and motivates us to make a purchase. It's a powerful force and an exceptionally unique category of content.
