Master of Puppets.
You must have heard it before, if not, i cant tell you how sorry i am.
MofP by Metallica is one of the most familiar songs from Metallica and it has great energy, song structure and melody. As a fan of Metallica i had access to look at things on youtube called "Synthesia" which shows you how to play things on piano, though, its rather limited.

I took that data and i used my imagination and other resourses to remix this song on Garageband.
(I need to upgrade to the Fruitiest of loops) 'o.o

(Had to repost song without original voice track clips)
