I was born in 90, lol. And considering DnB isn't exactly appealing music to little children, I think 08 is pretty early. Especially considering it was way before this dubstep craze.
I dunno man, I was in high school in the late 90's and it was already quite prominent.
Honestly though, instead of all the dubstep hate, why not just talk about the D&B you like?
I had a couple CDs (do you know what those are?!?
lol) that were D&B compilations. Some pretty good stuff on them. I'll have to dig them up and post some stuff here...
For the most part I find D&B too fast. My favorite electronic music is really hard to find, sort of a downbeat reggae with heavy bass. Similar to Dub (not Dubstep) but more modern. Like downbeat jungle i guess.
I also really like DJ Shadow but that's a whole other topic completely.
