Interesting that people seem to be in denial of what they ACTUALLY paid for (not perhaps what they WANTED to pay for), when purchasing music or other content.
Regardless of what you would like to happen, you only purchase a (limited) licence to use the content. So you cannot pass on your iTunes collection when you die. And you cannot (legally) format change the content. Nor can you broadcast the content in public. Or sell a CD while keeping an MP3 copy.
Of course, those who ignore the terms of the licence are probably too busy joining their fellow freetards and downloading pirated software to bother reading this.
