Funky key change at 2:47.

Dirt Dirt Dirt

I was watching videos with my son and saw this one.

Bang Bang

There is a nasty set of key changes at 1:35 and 2:12 in this rare version of Raquel Welch whaling on Bang Bang.

Spam/Stand

Yeah the original is by REM but I like Weird Al better.
The outro keeps changing to a higher and higher key.
-Trov

My Boyfriend

A big key change at the big commotion in the middle of the song and then two more changes in the outro.
 -Joanna

Leader of the Pack

A Phil Spector classic, the Leader of the Pack moves a half step up after the spoken word/motorcycle-sound-reel bridge.
