Saw this on Yahoo! Sports -- a list of the top ten songs heard at U.S. major league sports events in the 09-10 season, as reported by BMI. I'd suspect MLB baseball is over-represented in this sample of songs, since they play the most games per season. (And NFL football would be the least represented.)
I'm surprised at #10: Machinehead. It's a good sports song, but there are so many other hard rock songs of the same genre. Also surprised that some arena staples like Sweet Caroline, or anything by AC/DC, or Crazy Train didn't make the list.
And the folks at Yahoo! were wondering why Car Wash made the list. That's easy: because of the clapping part at the start.
