I, too, get what you're saying. I understand that you're looking at this from a DJ's perspective, whereas I'm looking at it generally in music-making.
I apologize, but my DnB songs all are, well, 160+ .How you said that 120BPM is way too low for DnB. Clearly, maybe it's a bit slow. But remember that as long as the song has characteristics OF the genre, it would still be classified as that genre . What would you call a song that was like DnB but was only 120BPM?
Lastly, the dubstep thing. Your video didn't list it either. Touche . Tags aren't everything. That song was clearly dubstep: You heard talking bass, drops, voices, and drum variations. Probably the best dubstep I've ever heard. And about, once again, the tempos. ...So you're saying that my dub songs, though they have all the characteristics of dubstep, but they're 20BPM higher - they're not dubstep?
Likewise said, I know that you're seeing this from a DJ's perspective. But as a proficient music-maker myself, I must say that variation and tempo does not change the genre. Infact, I'd say that it's a good thing to try something new, such as making a DnB at 120BPM. Or even, doing what I'm trying in Drum n Haste, and making a 210BPM DnB. Experimentation is very possible in the music-making world, and it never hurts to give new things a try.
I love you, but your attitude is like that of a shrew. Your options? Take a pill or be my kill. Might I suggest that you wear a vest. Perish in class or be banished to the land of bluegrass, where dreams don't exist as you'll be eternally pissed.
