DJ Fresh - Massive variety of songs, mostly DnB. Try
X-Project (WipEout HD mix).Sub Focus - A Drum and Bass master, though unafraid of trying other genres. His songs are extremely well crafted though, and possibly not your taste. Try his more insane DnB songs, such as
X-Ray or
Special Place.DJ Hazard - Extremely filthy, incredible Drumstep. The song
Machete is insane.
The Prodigy - While arguably Dance, the middle-age Prodigy music, such as the album "Fat of the Land" or "Always Outnumbered, Never Outgunned" is pulse-pounding electronic. Earlier albums such as The Experience or Dirtchamber Sessions are a more raw and powerful rave style.
Scooter - A bunch of Germans, thier songs vary from rave through to techno. Listen to a selection, they (like Sub Focus) have a large variety of styles.
Noisia - Usually steady, but in typical Dutch style Noisia have some truly "what the fuck" songs.
Split The Atom (also the title of thier album) is pure electronica, while
Red Heat is a rapid machine-gun of beats.
Alpha Centuri is a slow but bassy as fuck non-Dubstep tune, and quite fresh for it.
Diplodocus is just bass and beats. Clean, and steady.
Pendulum - Thier very early EPs and the album Hold Your Colour is a DnB spectacular.
Blood Sugar is insane.
Newgrounds - While a difficult trawl for good songs, the website
Newgrounds has an audio portal. Within, artists such as ParagonX9, Modem, alextheDJ and Hopeku craft some fucking insane beats. If you're after some links, PM me. I won't go trawling if you're not interested.
The song "Phat Beats". I can't actually remember the name, nor the artist, but it's probably exactly what you're after.
You'll know it by the line "Feel the phat bass running through your veins...it makes you feel alive"
I'm a massive fan of DnB, as you may be able to tell. Like all dance, the genre is interchangable - only the tempo and drums define a dance song.
Otherwise, what you're looking for is known as Eurotrance; phat beats and pure bass. No subtlety or symphony, but hey, s'your taste, not mine. Dutch Trance is also pretty fucking hardcore.
