What is your favorite Whitney Houston Song?

Growing up I always remember a Whitney song on the radio.

It seems like everyone of my girlfriends I spoke to this weekend we had a memory growing up of one of those Whitney songs where we would sing together.  Her songs and her music will just take me back to one of those great moments where we would blare the radio and sing- along.

What is your favorite Whitney Houston song....the one that possibly has those memories attatched to it?
