Oooh have to put my 2 cents in for my Top 3: "Papa Don't Preach" (or just about anything by Madon't-a), Patty Duke's "Please Don't Just Stand There" and "I Honestly Love You" by Olivia Newton John.
There is one song that is so hokey and stupid but I really like it: "Poke Salad Annie" by Tony Joe White. hahahaaa Whenever I play it, I turn it down real low because I'm afraid my neighbors will hear it--I could never show my face again! And one more song which I love but has just THE stupidest lyrics...Ry Cooder's "How Can A Poor Man Stand Such Times and Live."
There. I feel much better now.
