Is it just a bad second half of the year, or is iTunes run over? According to Blomberg, sales are declining. The news comes as I just opened up a delightful $25 gift card to grab new songs this Christmas. Interesting!

Apple Computer Inc.’s iTunes music store suffered a 65 percent slump in sales during the first six months of the year, reversing almost two years of gains, according to a Forrester Research Inc. report.

The number of iTunes transactions declined 58 percent between January and June of this year, while transaction size fell 17 percent, the Cambridge, Massachusetts-based market- research firm said today. ITunes spokesman Tom Neumayr said the report is “simply incorrect.”

“ITunes won’t save the music business, or Apple,” analyst Josh Bernoff wrote in the report.
