Not trying to be culturally exclusive here or anything...
They should take this song and hardcore it. If you removed that... what is it, a ryuteki? whichever kind of flute that is they use, and replaced it with another guitar and made that the primary riff with the other guitar still in there, that would be omg. Can also lose those 80s Orchestra Hits or whatever they are. This song has so much potential to be bad ass it's crazy.
sorry if that makes no sense, it just struck me.
