There's a low of 21°F in eastern Michigan today, but West Bloomfield resident Alex Ostrovsky is probably feeling just fine. Ostrovsky accounted for last night's 1 billionth iTunes download, the Coldplay track "Speed of Sound." For being one in a billion, Ostrovsky will receive a $10,000 iTunes music card, a 20-inch iMac computer, and ten 60-GB iPods. Apple will also set up a scholarship to Julliard in Ostrovsky's name. Legal online music consumption accounted for almost $800 million in worldwide sales last year, with an astounding 82 percent of American sales going to Apple. "I hope that every customer, artist and music company executive takes a moment today to reflect on what we've achieved together during the past three years," Steve Jobs said in a statement. I think Alex Ostrovsky would agree: we've come a long way since Metallica predicted the music industry's apocalypse and forced Napster's demolition.
