A European copyright law forced Bob Dylan to release a collection of outtakes to protect his own material. A "Use it or Lose it" provision basically says, "If you haven't used the recordings in the first 50 years, you aren't going to get any more."
So, Bob Dylan released various takes of songs recorded in 1962. About 100 copies of the 4-CD collection were sent to record stores across Europe. Now, those rare CDs are selling for upwards of $1,000 on EBay.
Dylan's debut album, released in 1962, did become public domain in Europe on January 1. That means anybody can use the songs without paying Bob Dylan. The reason for keeping the outtakes copyrighted, according to a source, is because, "we intend to do something with it at some point in the future."
