It's...personal really. I like the dubstep with the bass that literally makes your bones shake but don't like the BPMs on most.
Slow, nasty, dirty BASS.
But see i also love music like The Doors, Prince, Velvet Undergound, Orb, Eminem, Led Zeppelin, The who, Godley and Cream, The Prodigy, Mozart, Johnny Cash, Linkin Park, too many to list.
The long point IS that if you listen to a certain type of music often enough you will find a tune that hits you and your like "Okay, i can dig some of this"
Of course if you have to listen to 100 hours of any type music to find 1 tune you like then it probably isn't for you
Everyone knows and loves 'Auld Lang Syne' for instance right? But how many of those people actually like bagpipe music? Not a vast majority i would wager.
Subsonic Podcasts. Grab the first podcast and give it a go. If after the whole thing you don't like any of it then Dubstep is not for you

It has a little bit of everything.
