Stacy's Mom

The chorus jumps from A to C via the solo at the end.

Kyle's Mom Is a Bitch

Like all cartoon anthems, Kyle's Mom is a Bitch rocks a constantly changing key, with a half step rise after every verse. Comedic and musical genius.

Heaven

Track One from the Monster Ballads collection, featuring Jani Lane (RIP) on vocals. The last chorus modulates to Bb from its normal Ab.
-Kevin Jones

This Will Be Our Year

I heard this yesterday for the first time and declared it my new favorite song. I was happy to find a great key change at the end.
What a great tune...
-Tony Trov

C'è La Luna

Half step up with every verse, best song ever.
Sicily>Everywhere.

When I See You Smile

Your key change blog should just be a bunch of rock ballads.
Whole step up key change at the end.
-Nicole

Rock With You

"Rock With You" is one of my favorite MJ tunes. The key change at about 2:40-ish will rock you into the sunlight.

I apologize in advance if Celine Dion is singing for the first ten second of this video.
