Does anyone else feel that this song really isn't top-notch Yankovic? It's okay, but if I heard it on an album I'd have thought it was one of the tail-end songs; I'm boggled to think that he wanted this to be the lead single in his new album.
As well as him feeling this is strong, I think he probably puts a lot of weight on the public popularity of the song he's parodying when choosing a "lead" single. I suspect marketing parodies is at least as much dictated by the popularity and timeliness of the choice of source as the actual parody itself.
