You seem to have a problem with rave music. Allow me to explain the genres that confuse you oh, so much.
Happy Hardcore--Speedy, heavy beats, uplifting melodies, booming female vocalists (in recent years). There's actually a big difference between old-skool HH and modern-day stuff, but I'll leave you to figure that out yourself.
Gabba/Gabber-Also based around speed, harsh, distorted kicks, aggressive feeling.
PsyTrance-It's short for "Psychedelic Trance", an offshoot of trance music focusing on...well, they psychedelic feel. Often uses 303-acid synths. Usually ranges from 130 to 160 beats per minute.
Eurobeat-What, you don't like it? Bazooka Girl is the shit.
