It’s a sub-sub-subgenre of Hardstyle
The ordering goes
Hardstyle
Rawstyle
Rawtempo
So it’s like a blend between rawstyle and uptempo hardcore. The main defining thing is the tempo (160 bpm) and use of Zaag (Saw) kicks that originated in the Uptempo hardcore scene. I made a thread somewhere here about the genres of hardcore, you can read up on that if you want. The drop kick is unique. It has no transient, a monotone and super bassy tail, and quite often no punch, or a “beep” sound.
It’s a bit of an acquired taste, like most Hard Dance.
