Yo Hifiboom,
My main Style is Hardstyle , but i like the tunes that sound Hardcoreish, not the trancy stuff that really should be called hard trance. producers like The Prophet (A.K.A The Massochist, one of the pioneers of this style), Activator , Acti , Dj matti,Dj Rob. 140 - 150 Bpm is the usual speed of a hardstyle track.
I also like Dutch Hardcore , which is what I transitioned to after my Death Metal Days (Cannibal Corpse , Dying Fetus etc etc). I still listen to Hardcore when I need a \break from hardstyle. Most of the Stuff I listen to is the Darker side of the Mainstream songs, Just the Really Aggressive stuff, Not speedcore tho .. 160 - 170 (hardcore)bpm is fast enough for me, 220(speedcore) just rattles your brain out of your skull when your too close to the Subs
I will do A little DJ mix of what im into and upload for u to have a listen too will also give you A reference point of what I will be Trying to do with SCOPE
