Go Away Little Girl

I'm sorry but I can't hear this song without thinking he's singing it about Marie.
Either way, still a great tune.

The Happening

I always liked this song but never knew the name of it. 

Key change happens when Diana throws her arms up in the air.

-Tony

Opus 17 (Don't You Worry About Me)

Key change shortly after the saxophone solo, then up a half-step up almost every verse after.

-Joe Bruno 

Little GTO

This is the kind of rock and roll I love.  Commonly misattributed to the Beach Boys, this song rocks hard and drops a bomb ass key change after the guitar solo at 1:40. 
-Nick

Hymn

Epic. and one of my favorite key changes at 3:40.
