I'll have to explore more of the stuff in this thread. I wasn't a huge fan of Pretty Lights or the others... not sure what it is, but they didn't quite match the vibe of The Glitch Mob.
Honestly, GM has great beats, but what I really dig are their melodies. A track like "Drive it Like You Stole it" only works (for me, anyway) because of the melody, which is so catchy but also complements the rhythm really well. So anyway, I'm still exploring the whole EDM world, but nothing else has caught my hear like GM. They really seem to be one of a kind.
If I'm being dreadfully honest, I have a guilty pleasure in Mitis. I realize the guy is pretty much pop on EDM wheels, but I can't help but bob my head to his stuff.
