Dammit, voted Super Mario Galaxy without noticing Shatter was on there. SMG's a fine soundtrack but there's no risk of it not making it to the next round, so Shatter's the one that needed the support. For those who haven't voted: Hotline Miami and SMG are pretty much through, so vote for a straggler you're rooting for.
Also, vote for Shatter. The soundtrack was written specifically for the game, it wasn't just plucked out of a playlist like Hotline Miami's.
I love Shatter, but Hotline Miami's music fits the game better than most original soundtracks do, that is to say perfectly. I can't vote based on a distinction that would be invisible if it wasn't pointed out in the game.
Plus I think the Jasper Byrne tracks were original.
