West Bloomfield Township, Mich. ? Alex Ostrovsky got more than he bargained for when downloading Coldplay’s “Speed of Sound” from the iTunes Music Store.

The 16-year-old’s purchase was the one billionth song bought from the online music service that Apple Computer Inc. kicked off three years ago, charging 99 cents for most tracks. Ostrovsky’s selection was from Coldplay’s “X&Y” album.

The youth, who lives in the Detroit suburb of West Bloomfield Township, was showered with prizes: a 20-inch iMac, 10 fifth-generation iPods and a $10,000 iTunes gift card.

Apple also said it would establish a scholarship to the Juilliard School of Music in his name.
