Damnit @eversonpoe , you do too know what breakbeat music is, don't you?
"Breakbeat" (2), characterized, simply put, as a genre of around 140bpm with a kick drum on 1st and 3rd beats, and a snare on the 2nd and 4th beats in a 4/4 beat pattern. This varies the music greatly from the steady beat used in house, techno and trance etc., which while often sharing a snare on the 2nd and 4th beats, are characterized by a kick drum on every beat (from wikipedia) .
If you really don't know what breakbeat is, think most of the music of Crystal Method, The Prodigy (aside from their pure techno stuff a la experience,) a lot of Baby Anne, a lot of Kosheen...also the dj sets of Simply Jeff, Aquasky, Bassbin Twins, Icey, etc.
I would call Genesis. Oblivion and Flesh Without blood breakbeat tracks, for instance. MOST of her stuff is breakbeat.
Even her name is taken from pluralization of a breakbeat sub genre.
All of my favorite Grimes tracks fit neatly into the breakbeat genre, and the few tracks i DONT like happen when she ventures outside its tasty, groovy confines.
Just to be clear, I HATE endless "genrefication" of music. It drives me nuts when some geek tells me that he only listens to "progressive vocal psy-trance...but only the techy kind" or some ultra specific insanity. And i know it sounds ridiculously shallow to say that you don't like a genre of music because of where the kick drum falls. But that's just the way my ears work.
Also, human nature urges us to classify, classify, classify, and the only way we can describe music is with words.
I happen to LOVE drum and bass, jungle, breakbeat, dubstep and hiphop, while trance annoys me and i pretty much flat out can't STAND house music. I can't STAND 95% of what they are calling EDM these days (the 5% i like being the rare dubstep artist.)
