Completed and on site (http://www.ninsheetmusic.org/browse/series/SuperMario)
A beautiful piano solo (http://www.youtube.com/watch?v=XqryjQkusnw), performed by Koji Kondo himself unless I'm mistaken, that serves as the album's final track. It's an arrangement of the Rosalina theme.
Someone please do this! It's such a pretty song. I would like to play it for my recital if I could. XD

Right there, under Super Mario Galaxy.
Somehow I always forget to check on the site first. :P
Why haven't I noticed this?!
