I've beaten it as well. As I'm sure most of the users here have.
I haven't. I'm on the setlist that has Jessica in it. I haven't even completed all the bonus songs on hard. The only song left is Six, though, and not only is that song hard, but the song itself is so terrible it's offputting.
I just beat it two days ago. I had trouble beating Hanger 18 and Free Bird. Now Free Bird seems easy. I don't think i'll ever be able to 5 star all the songs. Beating it on expert is good enough.
I've beaten it. Five-starred all of the main songs except Psychobilly and Misirlou.
As of now, I recently beat GH2 on hard using only two fingers. Five-starred most of the songs, but a lot of the later ones and a few from the early tiers are only four-starred.
I did. The only tough song of the final tier was Hangar 18. Freebird was a let down.
