Guitar Hero III

Your first opportunity for this achievement will come early in the Medium career. I did it on "Story of my Life" by Social Distortion, located in the fourth block of the first tier. If you are finding it hard to get it, don't worry because you get another chance later on in the career. The next available song for this achievement is "One" by Metallica. It is the last song on the eighth tier before the final boss battle. You should be able to easily get 275,000 if you're good at the song, and use Star Power at the right moments. After a couple of plays, you should be able to get it.
