Are any avid listeners of the aforementioned umbrella of various subgenres lurking around here? Often known as j-core as in hardcore techno, but it's more like a scene with various genres. Consisting of stuff like trance, happy hardcore, speedcore, gabber, makina, hardstyle, wubstep, dnb and some other (chipmunk vocals, touhou covers, harsh noises galore). I consider this a guilty pleasure like listening to italo-disco. However what ties all this together is the fast tempo. To me this stuff is very enjoyable when I'm spun.
Here's some examples:

This is still a very young genre and majority of the releases can be found from rutracker in complete label packs.
