Springsteen Debuts Net-Only Single

While some artists battle online file sharing networks, others have embraced the new market for digital music. Bruce Springsteen is launching the first single off his upcoming album, "Devils & Dust," exclusively on the Internet via AOL Music and Apple's iTunes Music Store.

"Devils & Dust" won't be available in stores until April 26, but will feature special content using the DualDisc format, which functions as a CD on one side and a DVD on the other. Apple isn't the only company shoring up exclusive tracks; Microsoft recently announced it had signed Mariah Carey to debut her new single on MSN Music.
