I would argue it does hurt, because it ques the fans in the stadium to "check out". Trust me, it was louder before the piped in music. Two words always come to mind when I hear it. Lame. Contrived. The attendance issues run far deeper than a lack of "Sweet Home Alabama" during a TV timeout. In fact, I'd argue that by giving into this trend of chasing shorter attention spans, you're actually making it worse. You're taking away the uniqueness that is college football and ultimately that's what's going to draw people back (and winning, of course).
