You can tickle me pink, orange, red, or blue, but not grey
I-tunes is the biggest (and most popular, most known) music store in the world, has been around for 5(?) years, and is part of one of the biggest companies in the world, Apple. If they were stealing the music off of the artists don't you think there would be a million lawsuits, they would be closed down, all over the news, and in jail? Also Apple has a reputation to keep and build upon. Also the artists have to give their consent to sell the music on I-tunes. They don't just wake up one day, go on Apple, and out of the middle of nowhere see their music on there.
Also since now a days people buy more music digitally then physically, and the artists are obviously (when you look at their lifestyles) making a profit from something, it's safe to say that they get a profit from I-tunes.
Because grey will not do.
