any songs that you've heard or like.....repost from BHB

Is there any songs that would be good to play at our wedding? Cake cutting, enterance songs. I am going blank!!! We need to hand our final songs in 2 Weeks. I don't think we are going to do the macarena, chicken dance or whatever those corny songs are.
we haven't even decided our first dance song. It's either Shania Twain-Forever and Always, Atlantic Starr-always, or Lifehouse- you and me
Any suggestions are helpful. Thanks!!!
