Apparently Virgin Records and EMI are doing something like this already. While looking through the booklet to the new A Perfect Circle - Thirteenth Step (in stores now!) this little message from EMI was on the inside page: "Thank you for buying this music and for supporting the artists, songwriters, musicians and others who've created it and made it possible. Please remember that this recording and artwork are protected by copyright law. Since you don't own the copyright, it's not yours to distribute. Please don't use Internet services that promote the illegal distribution of copyrighted music, give away illegal copies of discs or lend discs to others for copying. It's hurting the artists who created the music. It has the same effect as stealing a disc from a store without paying for it. Applicable laws provide severe civil and criminal penalties for the unauthorised reproduction, distrobution and digital transmission of copyrighted sound recordsings.
