Nine Inch Nails just released Ghosts I – IV, an instrumental double album. The first 9 tracks are free to download, while the entire album is available for download as high quality mp3s for $5. An actual CD copy is $10. This is the first album Trent\’s released completely independently and free of any contract with any label. It\’ll be interesting to see how successful this is (the insanely heavy traffic to the site might be a good indicator).
