Why would you "download" or "copy" something that someone wants you to pay to have the rights to do so? boycott more power to you, steal more power to them... you just don't fulfill your contractual obligations... and please don't tell me this movie/song/vg are so great that you can't buy them but have to "steal" them... respect the copyrights of others if you want yours to be respected...

Because I have an old cassette tape of the music and want it in digital and don't want to bother doing it myself?
Because I have a cd that got scratched?
Because I had it downloaded in stupid Realplayer format and had to go to machines that didn't support that idiotic thing?
Want more?
Oh, wait, you want us to PAY MULTIPLE TIMES FOR THE SAME ITEM?really?
If you buy music (or a movie, book, or a tv show) from iTunes then you can download it an unlimited number of times (or even not download it and only stream it to your device). The same is true for many other cloud/online music sites
