Are there any websites where I can find notes of the songs so that I can play it on piano?

Answer 1

There are quite a few, it seems. Here are links to some I found. You should be able to find something at the standard you want.

http://www.pitt.edu/~deben/freebies.html (seems to be fairly elementary but easy stuff is not necessarily poor quality!)
http://www.8notes.com/

Thanks, too, for your answer to my question. I tried to send you a message but your email has not been confirmed.

Answer 2

www.google.com or www.yahoo.com! In search box write: notes for piano.
