I finally beat GH2 on expert. Freebird was a bitch. When you fail the song after playing it for 8 minutes and notice you only got through 80% of the song, it sort of dashes your desire to play it again. So far this is the first song that I actually had to practice on.
Once you play this on expert for a while, hard seems waaaaay to easy. After I beat Freebird, I went back to hard and got 5 stars on Misirlou, Institutionalized, and 4 stars on Psychobilly Freakout. Up until that point I wasn't able to get more than three stars on Institutionalized and Psychobilly Freakout.
Now I'm thinking of making Institutionalized my "show-off" song. I hate to admit it, but that song is starting to grow on me.
