NJoy, I am right there with you on the Big Butts and You Can't Touch This.... I am a hopeless romantic so Moon River, sung by Andy Williams always gets me. Rocky Mountain High by John Denver (played it while I was giving birth to my first born). I'll think of more and will come back.
I can't remember if I posted this yet or not, but, for all M.C. Hammer closet fans, this is awesome....
