What song is Lex playing on piano?

Question

On the new episode of Smallville that showed Thursday, December 7th (The show was titled Subterranean I believe), what song is Lex playing on the piano about 32 minutes into the show? Someone said New Born by Muse, but I'm not quite sure about that.

Answer 1

I only found two songs listed for that show, but maybe they don't list the piano song. Here they are:

Miss Murder
Summer Shudder
