In a very short period, Apple has definitely changed the way we listen to music. iTunes will quickly be reaching one billion downloads. I was sitting here trying to calculate the percentage I’ve contributed to that billion, and it’s pretty high.

To reward users for this milestone, they are giving away a $10,000 iTunes Gift Card, an iPod touch, a Time Capsule, and a MacBook Pro.

Users are entered automatically upon completing a download, or you can enter without a purchase here. I have a few songs I’ve been meaning to download, so I will definitely throw my name in the hat and cross my fingers to win, and also watch to see how quickly the counter reaches 1 billion.

The official rules of the contest are listed here. If you win anything, be sure and come back here and rub all our faces in it and/or thank us for sending you over there to enter!  Good luck!
