the difficulty level differs based on the genre. Like...easy in classic is almost similar to difficult in hip-hop

What in the blue hell are you talking about? The difficulty levels are SUPPOSED to be the same in general. You can't say, for example "OH NOS EASY IN DANCE IS EASIER THAN EASY IN ROCK" or something like that. Yes it's the true the ratings are messed up, but if you know which songs you can do and which ones you can't, the whole song rating thing isn't really all that important at the moment. Synth will eventually get to fixing them, but let's not forget that he has work, a family, and a life of his own. If he fixes it soon, great, if not, just wait.
