My Favorite Song

Someone asked me today what my favorite song is. I was left speechless--like, you mean, favorite song of all time?!?! What a horrible question. I can't answer it. I'm quite certain that my answer would change before it even left my mouth. "Baby Please Don't Go"? "Amazing Grace"? "Stranglehold"? "Redemption Song"? "The Bed's Too Big Without You"? 'The Thrill Is Gone"? Something by AC/DC or Aerosmith's version of "Train Kept A Rollin'"? I have no idea. I fully suspect that if I truly tried to answer this question I would end up in an insane asylum.
