Rock Revolution (EU)

"Blitzkrieg Bop" is the best choice here due to it being the shortest song in the game, load it up on whatever difficulty you play, strum like a maniac until your highway is flashing red and then stop strumming like there's no tomorrow and show the crowd what you can do, the achievement will pop at the end of the song, just remember to get out the red in time!

It's worth me pointing out that you don't seem to be able to fail a song, so don't worry about that happening!
