iTunes Exclusive Track Breaks Billboard Top 10

Macworld notes that for the first time ever, an iTunes Exclusive song has debuted in the Billboard Top 10.

The track (iTunes Link) was "I'll Stand By You" performed by Carrie Underwood during last week's American Idol "Idol Gives Back" charity episode. Macworld reports that the song has been purchased over 100,000 times in less than a week.

Of course, while most of the boost in sales reflects the cross promotion from a popular television show, it still represents a notable shift towards digital music sales.
