I don't own all the RB songs, that's for sure, but I swear this is the worst guitar chart i've ever played. The uber-impossible songs like the ones from chaotrope and dragonforce, as well as pulse of the maggots are insanely hard, that's for sure, but it's understandable, and TOLERABLE. This chart is not. Wondering why pro guitar chart is only 3 dots? because it's easy. Not finger crossing like this stuff. It's seriously not fun at all. They could have charted the riff part as GR-RY-GR with HOPOS and none would complain.
