Apple has launched a countdown to the one billionth iTunes track sale.

Currently the ticker is on 951,060,444, 445, 446…

As has been the practice with previous iTunes countdowns, the person who purchases every 100,000th song will receive a prize package.

The prize is a black 4GB iPod nano and a $100 iTunes Music Card.

The person who downloads the billionth song from the iTunes Music Store will receive a 20-inch iMac, a $10,000 iTunes Music Card, and 10 60GB iPods. How popular will they be!

In addition, Apple will create a full-ride scholarship in their name to a world-renowned music school. “Just think: You could help launch the careers of an entire generation of musicians,” says the company.
