Many countries have a "blank media levy," which is basically a tax on any kind of blank media on the assumption that some percentage of the blank media bought is used to make unauthorized copies of music. This is pretty ridiculous for a variety of reasons -- most notably the assumption that everyone is breaking the law and needs to pay a tax to a single industry that is unwilling (though not unable) to adjust its business model. However, in Sweden, one musician who started receiving his "royalties" from such a blank media levy was so offended by the concept that he decided the only way to pay the money back was to use the money to fund a new "Pirate Album"
using samples and clips from other musicians, put together to make totally new songs -- and then release the whole thing on The Pirate Bay. He's using the album to highlight how ridiculous it is to forbid others from making new derivative creative works built on the works of others. If only more musicians would realize that all creativity is built on the works of those who came before, and pretending that the line stops with you is a mistake.
