Songs with piano in them?

I am trying to find some awesome/really moving/powerful songs that have piano in them. I am trying to find somewhat "newer" songs (down the line of chiodos, mayday parade, etc). We all know the following groups have used the piano: ELTON JOHN, QUEEN, BILLY JOEL, KEANE, COLDPLAY, THE BEATLES, etc. So please don't recommend songs that are blatantly obvious (like the artists mentioned above) I'm trying to find great songs, that might not be well-known. Lets find some good songs people. Thank you.
