Who plays that piano song off of the movie "The Last Song"?

I want to know who plays that song with the piano off of The Last Song movie. Not the Steve's theme song(the song that Ronnies dad makes for her), but the one where Ronnie met Wills parents and they talk about Wills brothers death. That scene. I tried looking for it on the soundtrack, but it's not listed. Does anyone know what it is?
