I'm going to go with "Casimir Pulaski Day" by Sufjan Stevens.
But of course are some contenders:
-Against Me! "Don't Lose Touch"
-Descendents "Suburban Home" (Could only find a live version on Youtube)
-The Beach Boys "God Only Knows"
-The Beatles "I'm Looking Through You"
-Buzzcocks "Ever Fallen in Love With Someone (You Shouldn't Fall in Love With)"
-Coconut Records "West Coast"
-Ben Folds "The Luckiest"
-Rilo Kiley "Science vs. Romance"
-The Rolling Stones "Paint it Black"
There are plenty more but I think you get the idea...
