The latest update to the official Super Smash Bros. Brawl site is a second music track.  This time, it's a new arrangement of the ending theme to Yoshi's Story!  This particular track was arranged by Masafumi Takada, composer of the decidedly un-Yoshi's Story-like game, Killer 7, as well as music producer of Samurai Champloo: Sidetracked and God Hand.  Click the link below to listen.
