Fangirling about Shingeki no Kyojin aside, this is an amazing song. Played by two people whose piano skills are out of this World.
Of course, this theme is perfect for SnK regardless. The amount of ass kicking involved suits this adrenaline filled song entirely. Mostly done by the almighty Corporal Levi-sama. And maybe Eren as a Titan. Maybe.
and then much … spinning,
more spinning~ 
And generally, a short but hot guy with this unexplainable attractive haircut that pwns all.
(At this point, I realised I should do separate posts about all my fandoms before my brain explodes with their sheer awesomeness.)
Not even kidding. I personally have Grade 8, which already stretch me too thinly and I can’t even explain how that miracle happened, but only that it did. However, we’re talking about another level entirely. When you reach this level, it’s almost as if you’ve achieved the status of a deity. Animenzzz and Tehishter. You guys deserve a -sama after your name.
Technically, this is a challenging piece of music for sure. The duet also means it’s not easy having to cooperate with another person, tempo wise – it’s a tough job. Then, let’s not forget that this song is sung with a whole host of guitars, drums etc. etc. You’re doing this on a piano. All of it. And it sounds good. Scratch that. OUT OF THIS WORLD, AMAZINGLY AWESOMESAUCE.
When I listened to this (for the first time, of many)…
When can we start building the shrines and worshipping you guys?
