Neversoft did a smart move when they released the boss battle tracks as solo song for free... Some of these songs were well put together and most people just wanted to enjoy playing it without having to play the battle mode...

Tom Morello really did help out with Guitar hero 3 and decided to perform a solo with shows off just about all the sounds he can create with a guitar...

Also to just show the difficulty of the song on expert mode, I decided to show a random person performing the song, therefore please be mindful of one or two parts where it scratches a bit (when he makes a mistake...)
