Justin Beiber doing Johnny Cash!? JUST NO!
How bad do you wanna punch this kid in the face? Johnny Cash, don't you dare! Who do you think you are kid?
Here's my favorites of all-time in no particular order:
Johnny Cash
Foo Fighters
Metallica
Three Days Grace
Weezer
Sublime
And Johnny happens to be the coolest person that ever lived with music that has stood the test of time, music that is imitated but never duplicated. This is a musical crime and he should be assaulted with his own guitar. Screw this kid!
