Back At One

Brian McKnight did it first. Tennessee Winston Luke did it best.
-Dave Kiss  

Hold Me, Thrill Me, Kiss Me

One of my all time favorite songs. Made popular by Mel Carter, I'm slightly ashamed I just realized it ended with a key change.
Perfectly executed and maybe the most romantic song ever made.

I'm Every Woman

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

One Moment In Time

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

Gonna Have A Funky Good Time

Heard this at work on  the soul Sirius station.  There are many versions of this song on YouTube but it took me a while to find the full version.  Most versions fade out at 3:30 for radio or Soul Train standard format but in the original the key change comes at 3:47 when James asks the band to bring it down so he can get funky deep.
"We gotta get down and in order for me to get down we have to get in deep." - Sir James Brown

Con Te Partiro

Made famous by Andrea Bocelli during PBS's 1997 holiday membership drive, "Con Te Partiro" features a key change just after the midpoint. Here is a wonderful Spanish-translated rendition of the song, "Por Ti Volare."
-Al Bruno

The Youth

Fantastic key change in this song at 2:36.

Always Be My Baby

I heard this at karaoke.
