Apple has launched a new promotion counting down its one billion song milestone for the iTunes music store. “Music lovers like you in 21 countries around the globe have purchased nearly one billion songs from the iTunes Music Store. And as we count down to this massive milestone in digital music history, we’d like to thank you for joining us. We’ve got one billion reasons to celebrate, and we’re starting with you. As we mark our way to one billion, the music fans who download every 100,000th song will receive a prize package featuring a black 4GB iPod nano and a US$100 iTunes Music Card.” The grand-prize winner who downloads the billionth song will receive a 20-inch iMac, 10 60GB iPods, and a $10,000 iTunes Music Card. In addition, Apple will create a full-ride scholarship in the winners name to a world-renowned music school.
