How about:
"Always Be My Baby"-Mariah Carey: '...I'm part of you indefinitely...no way you're ever gonna shake me, ooh darlin', cuz you'll always be my baby'
"Never Gonna Give You Up"-Rick Astley (the title alone is creepy enough, coupled with the fact that it's, well, Rick Astley)
"Father Figure"-George Michael: 'Nuff said.
"Untouchable Face"-Ani DiFranco: The whole song is stalker-iffic. Favorite/creepiest line: "...I could make you happy, you know, if you weren't already. I could do a lot of things...and I do." HELLO, threatening stalker chick!
and perhaps the ULTIMATE creepy love song...
"I Put A Spell On You"-Nina Simone/Diamanda Galas.
SCARRRRRRRRYYYYY!!!!!! (And I LOVE IT LOVE IT LOVE IT!)
Suzanne: I never use catalogs. I'd rather go in the store and see all the salespeople groveling and sucking up to you.
Julia: Pardon me, I never knew they were so solicitous at the K-Mart.
