Frozen. By far

I agree with those who have said Live to Tell.
I think my favourites are Like a Prayer, Vogue, Sky Fits Heaven, La Isla Bonita, and Cherish. I listened to one of her new songs off of Madame X, and wondered why I ever liked her.
I'm going to say Cherish. It makes me feel happy.
Rain was pretty amazing as well.
