Still got a kind of buzz to it, but it's more refined. ((this track in particular is pretty 'epic', I always imagine it as like some transformation theme
Portal 2 uses that sort of sound in a few places, the 'glitchy but smooth', clean synth filtered to achieve the harsher scratchiness i guess. Some others might be worth listening to in that respect -

((good music, full ost has a wider range than what's above but those are somewhat 'similar' in mood to me. you can actually get the whole OST free and legit through the official website http://www.thinkwithportals.com/music.php which is pretty awesome of them))
