Chipmunks & Chipettes - I Gotta Feeling

Title says all! I added a cool effect that the poeple who are singing go into colour when people who are not singing go black and white! Bonus Track for Alvin and the Chipmunks: The Squeakuel! Remember chipmunk fans, Alvin and the Chipmunks: Chip-Wrecked is coming out on December 16th, 2011!
