Super Mario Sunshine - Secret Area
By Impossible

The parts on the left (1, 3 and 5) are the main parts that are
intended to be played. The parts on the right (2, 4 and 6) are
quieter doubles of these parts with different instruments, and
the song will probably sound better if you stick to playing the
ones on the left. 7 and 8 are just bass and drums respectively.
