it sounds like happy hardcore genre to me
Happy hardcore was between '95 and '99, and has a very distinct sound imo:
Although Dancecore/Mashcore definitely has some elements from it like the fast breaks and kicks it differs in that it necessarily mangles existing pop music or known hooks to build up the music. It also often goes way faster/more abrasive/experimental than happy hardcore ever does.. there just isn't anything else like it really (shitmat and bit meddler kinda had the right idea..)
I showed it to a couple of different people midway hyperpop discussions and they immediately associated it with the genre. I find it interesting considering that dancecorps was alive and kickin back in '09 already.
