Man, they have some seriously gay songs on it, but there are a few cool options as far as touring and junk goes.
I'll probably pick up the disc this weekend. I'm holding out for GH:World Tour for the instrument set, though.
I agree about the songs. More chick songs. I don't car much for female singers. I have been playing it just so I can sing, "Shooting Star".
I know someone who works at Harmonix so I'm automatically biased against the new GH...but whatever, Guitar Hero copied Rock Band and that just makes 'em look lame anyway. >=P
