my list is rather short

Chris DeBurgh - Lady in Red (if i hear ONE comment about prostitutes here i will smack whomever says it)
Gwen - Don't Speak (ok it's the best 90's slow dance/"am i punk? i'm not sure" slow dance song)
Put Your Head on My Shoulder - I'm not sure who sings this. I heard Bobby Klemple do it and was suitably impressed. It makes me want to live in the 50's.
Frank Sinatra - I Won't Dance
Norah Jones - Don't Know Why (I can imagine being like 40 and slow dancing to this with my wife under the stars after we've locked the kids inside the Nissan Pathfinder watching "Lion King" on DVD)
Dean Martin - You're Nobody Till Somebody Loves You
Bobby Darin - I'm Beginning to See the Light
Bono and that Ridiculously Hot Chick from the Corrs - Where the Stars Go Blue
Frente - Bizarre Love Triange (this is the slow version...this is, without a doubt, my FAVORITE)

The World's GAYEST song

"Last Dance" - this is played at weddings to confuse people. It starts out slow, but then turns fast and horrible. And the only reason it gets played is so people get the hint and go home.
