I saw the U2 iPod commercial last night, and all I can ask is, what do they have to prove? I mean, didn't their last album sell a metric ton? Don't their concerts sell out within hours? And don't they do this consistently? They've never struck me as a band to do commercials. It can't be for the money and it can't be for the exposure. So what's the point? I haven't been this confused since N'Sync started doing Chili's commercials a few years ago.
