Its not your music. Its the label's music. They are charging more for you to own a higher-quality, less imposing license music file. Just like I can buy Apple's OS X Server for 10 clients at $499 and their unlimited client at $999. Its not MY software - its Apple's.
A product is not simply the binary bits it comes with, but the agreement that it comes with. When you buy Photoshop, you do not "own" it. You can't go and make 10,000 copies and give it to your closest friends.
So the real question is - how much more idiotic can you and others like you get with your attitude?
Spot on! Some folks really don't understand the concept of a license. And it's not really too hard to grasp ;-)
