Ummm... no. You're NOT buying the tunes from Apple, at best you're renting them. If you don't believe me then here's an experiment:
Go to your favourite music shop and purchase some music on CD or vinyl. Now go home and listen to it. Listen to it in your car, your office, wherever. Decide you really like this music and your friend would appreciate hearing it at his/her leisure. Lend the CD/vinyl to them to listen to wherever they want. Eventually (hopefully!) they return the CD/vinyl to you. You listen to it some more. Eventually you die (sorry, but it's going to happen to all of us). In your will you leave thhe CD/vinyl to somebody you like so that they can listen to it as much as they want, or lend it to their friends. When they die they too can bequeath it to somebody.
Now repeat the experiment with music "purchased" from Apple. You can listen to it wherever you have the technology to get access to it - great. Now try lending it to a friend... or bequeathing it in your will...
Maybe I'm old-fashioned - actually I *AM* old-fashioned - but to me "purchasing" something means that it's mine to use and dispose of as I wish, not as the "seller" dictates.
