I'll get to Rock In A Hard Place next, right now I'm on Night In The Ruts. Steven Tyler was of course a miserable drug addict to this time.
Regarding the Taylor Swift discussion below, it's pretty funny when newcomers to the video don't realize that Taylor plays both the good girl and the bad one, though as you pointed out they both have 600 pounds of makeup on.
The prospect of her becoming a $cientologist is a pretty dire one.
But in all seriousness, "You Belong With Me" is the one post-2000 song I think I've heard in public more (grocery stores, bars, restaurants, walking past TVs that had the video playing, etc.) than any other barring U2's "Beautiful Day" which would still easily be the champion.
