Keep An Eye On Summer

"Keep An Eye On Summer" by The Beach Boys manages, amazingly, to cram four key changes into a 2:25 song: Gb to Bb to Db, (moving up the Gb major triad) BACK to Gb, and finally finishing in G. If this wasn't enough to prove the work superior to lesser songs with standard I-vi-ii-V chord progressions, couple this insane structure with the rich, incredibly complex vocal harmony arrangement and it's easy to understand what made Brian Wilson such an effing genius.

Out in the Fields

Nifty modulation propelled by the synth part.
One of the Rambo movies totally should have used this tune. I'm a huge Thin Lizzy/Phil Lynott fan, and loved Gary Moore's work with them. This is good for what it is. Was really sad about Moore's recent passing. One of the best

What Becomes of the Broken Hearted

A key change can be heard in this famous Jimmy Ruffins tune, modulating from A in the verse to B in the chorus.

Nothing But Flowers

I know someone told me this song had a key change in it but I can't remember who referred it. It just popped up on my iTunes and refreshed my memory. Whole step key change at the end.
I first heard this in my least favorite Kevin Smith film Clerks Two.

Back To The 101

When Albert Hammond Jr. wrote his solo album, it made the world realize that the reason they actually like the Strokes is because of Albert Hammond Jr. Awesome key change here at 2:37. It goes down a half step (always cool when the key change goes down) and the lyrics change from "Back to the 101" to "I count the 101." Killer album, fried and frizzy hair, silly strats, and kickin key change.
