Setting aside the (I'd say) dismal player ratings thus far, I want to congraulate you on the rank. Also nevermind me being late.
The DaRRi difficulty doesn't seem to have much for variation in mapping structure. But instead the map is so well-attached to the song it's left an awesome impression on myself.
It's funny, I'd rate it the highest of 10, solely because the map is as such, and in good effect makes me enjoy the song itself a whole lot more.
Extra notes: Now, not meaning to say here that having a Gangnam map automatically decides a 10 rating by itself, but rather I am here simply to show my deserving appreciation for the map/mapper at hand.
