Rio

I don't usually post songs that have parallel minor key changes but this one is just so great.
Duran Duran rides E major and E Minor like the schooner in uhhh Rio.

Chain Reaction

'Chain Reaction', performed by Diana Ross. If I'm being conservative, I can hear five changes. If I'm being liberal, I can hear eight changes. Haha. I reckon there are half-steps into each chorus, and then into each repeat. Two after the break, and two in the outro.

One Heartbeat

Play that saxophone.
The hooks are key changes. 
-Frankie

Smiling Face

A has a couple of nice key changes.
A whole step jump between verses.
