Whats an easy but good song to play on the piano?

I cant play piano very well but i need an easy but good sounding non-classical (if possible) song that i can learn for my music industry class. Thanks.

Apologize by Timbaland. It's a really good song to learn, you will impress everyone and sounds really good on the piano. Youtube it, there are quite few tutorials on it.

Here's one I found
