Been following him for quite a while now. The style he (and killsteal) does grew a lot in popularity recently, in particular last year. Lots of newcomers are doing similar things, particularly those who recently started producing music since it seems to be a very beginner friendly sound. Probably 20+ people doing it really well now.
Personally I'm forced to mostly ignore his work since the songs are mostly too bright for Nightcore. Good on its own though :)
