How Will I Know

Wikipedia says this song was originally intended for Janet Jackson, but she passed on it. The key change is heralded by a saxophone that was not present for the first 3/4 of the song, because obviously. It is sneaky though- sounds like it goes up, but it when the chorus comes around again it’s actually sung lower. Oh man the 80s were great.

Where Do Broken Hearts Go

This is the kind of song i would listen to on repeat in 8th grade! and i think there's a key change at 3:05.

I'm Every Woman

A  Chaka Khan cover, the proof is in the pudding.

One Moment In Time

Right after 3:22...booo-yah!!

I Have Nothing

This is such an unbelievably dorky project, and I love every bit of it. The key change hit its peak with ’90s divas and this blog sheds light on some of these anthems, however Whitney Houston’s key change in “I Have Nothing” (the greatest key change of all time) is surprisingly missing from the list. Somewhere, underneath a pile of white dust, a legend cries.

I Will Always Love You

A classic pop radio key change. Song starts off in A major, at around 3:05, we get set up for the key change with an E major, which then brings us to the chorus in B major. The scene behind Whitney Houston in this video changes as well. Does that mean I get extra points?
