In a blow to the future of the first sale doctrine—the law that protects your ability to lend, sell, or give away your copy of books, music and other copyrighted works—a federal court held today that the Redigi music service, which allows music fans to store and resell music they buy from iTunes, violates copyright law. According to the court, when it comes to music, you may have bought it, but you don‘t own it, at least if the „it“ is an mp3 file rather than a CD.
