Linked a facebook page where Noel explains the confusion with the track titles which caused the liner notes to be inaccurate. The credits in the liner notes for "Gravity" (1.19) actually correspond to the game's ending theme "Like a Phoenix Rising". The post also confirms DJ3no as the vocalist on "Gravity". Also, Noel is indeed the same person as Noel Smith who did some choir work on the album.
