Sounds like it's time for me to dump links!
As with others here, I'm not a fan of what people refer to as "true dubstep", but I like dubstep elements infused in other genres (particularly Electro House). In fact, most of Skrillex is a blend of Electro House/Dubstep. Anywho, a small sample of songs I like!:
Dubstep/Electro House:
Porter Robinson - Spitfire (Kill the Noise Remix) Epic dirty fat synths!
BT & Adam K - Tomahawk All sorts of genre mashing goin on here.
Mord Fustang - A New World Holy crap Mord Fustang is all sorts of awesome!
Mord Fustang - Lick the Rainbow Less dubsteppy, but again, Mord Fustang is all sorts of awesome. 'nuff said.
Asking Alexandria - A lesson Never Learned (Celldweller Remix) .. METALSTEP!!!
Motionless in White - Creatures (BEAST Remix by Celldweller) .. DARKER METALSTEP! (Possibly has one of the, uh.. 'hardest'? drops I've ever heard)
Dada Life - Happy Violence These guys are srsly insane, but srsly awesome. (Electro House only)
Vocal/Uplifitng Trance:
Lange feat. Emma Hewitt - Live Forever (Mat Zo Remix) Mat Zo is probably king of "Uplifting Trance". What makes it uplifting? Probably being in a major key
Above & Beyond feat. Zoe Johnston - You Got to Go This one keeps getting stuck in my head
Mark Eteson. feat Audry Gallagher - Breathe On My Own (Daniel Kandi Remix) Vocal and uplifting!
Trance:
Aly & Fila vs Philippe El Sisi feat. Senadee - Without You (Nhato Remix) WHO IS THIS NHATO AND WHERE DID HE COME FROM!?!
Bjorn Akesson - Painting Pyramids (Nhato Remix) AGAIN, WHERE DID HE COME FROM?! He has probably the best sound I've ever heard!
Ferry Corsten vs. Armin Van Buuren - Brute This is one of the more popular trance tracks of 2011.
Super8 & Tab Feat Betsie Larkin – Good Times (Lange Remix) Some of my most favorite songs were created or remixed by Lange. Great stuff!
Gareth Emery feat. Christina Novelli - Concrete Angel Gareth Emery also has loads of good stuff I could list here.
Stoneface & Terminal - Leaving Earth Another great trance group
Tritonal - Lifted (Feat. Cristina Soto) Tritonal has some awesome trance, too! (Okay, I'm done with trance now)
Drum N' Bass:
Pendulum - Witchcraft Pendulum is probably one of the more popular Drum N' Bass producers. Good stuff!
Pendulum - Self vs. Self (feat. In Flames) Metal N' bass? METAL N' BASS!
Glitch Hop: ..?
Opiuo - Loist Moinal Came across this song a while back, interesting genre, but insanely groovy beat!
Ambient/Experimental:
BT - Our Dark Garden It's good to stop and meditate every so often, right? Definitely one of my favorite pieces.
BT - The Antikythera Mechanism BT is a musical genius, and some of these pieces show off his talent. (You should check the rest of This Binary Universe album if you find it interesting. I would recommend listening to the music once before watching it with the visuals, but that's just me)
Okay holy crap I'm done now. I'm getting out of here before I find something else I forgot to add X|
