Well, it isn't the actual achievement that was difficult. But I beat Guitar Hero: Aerosmith on Expert in roughly 4 hours.

aerosmith is FUCKING BORING, I played gh3, expert. got to ttfaft until herman solo 2 (sooo gay)

Yes I have five star aerosmith.

I have wii version so no achivement. but I could say 700k is pretty hard.
