Doe anyone know the title to this clical song?

Okay, so I was watching the new criminal minds episode yesterday that heired on Feb. 23, the one about that kid called Sammy who was blind I think and both his parents were kidnapped by this delivery guy that meets Sammy at the music store and plays a clical song on the piano throughtout the episode, so i was wondering for those who watched it.... Do you know the title to that piano song? I like it alot and I want to know where I can get it from, but I'm not sure if it really IS a piano song, or something the TV show just made up. If you know it, can you please tell me??? Any answers are appreciated!
