Tracks that are catchy, rockin', head-bangin', or just particularly well-charted. No meme charts, or tricky gimmicks here, just excellent songs with excellent charts. A lot of work goes into making a good chart and so far (for my tastes) these are some of the best of the best! I will only vouch for the Hard difficulty for now since I can't really touch impossible. Also, you probably won't find any anime-type songs or japanese K-pop or whatever, cause I'm just not into it!
