The Fun Way To Learn To Play The Piano

Anybody know a cool, fun, easy and modern song that I can play on the piano?
Hey, I’m in the mood to learn to play a new song on the piano.
Does anybody know a cool modern song that’s fun and easy to play?
I would also like it if somebody could tell me a title of a piano piece that is very, how do I say, emotional?
One that has like strong and sad pieces– but still pretty rythmical… I dunno I would just like to play such a piece (and I’d prefer if it were a modern piece as well which I believe is not easy to find… maybe a modern sad song — like “Moby – Why Does My Heart Feel So Bad” but with more melody parts in the piano sheets…
I know this is a pretty demanding question :p but I really want to play such a piece— I feel that I need to work out my arts a bit more (I didn’t do 5 years of piano when I was small for nothing!)
Anyway, unlimited gratitude to anybody who can give me a cool song ;p

Superman (It’s Not Easy) by Five For Fighting is an awesome, powerful song. John Ondrasik performed it at The Concert for NYC, which honored the police and fire personnel after 9/11.
