I honestly don't see what the hype is about. Disclaimer, I'm a huge CV fan and not a big Shnabubula fan, though I do consider Castlevania Chronicles Mucho Dollar Care a Junk CIA to be quite nice.
Shna's style is all over the place, there's too many textures competing with each other which leads to this song sounding like a bunch of randomness layered over the original tune. I'm sure it was hard, I'm sure it was a musical challenge of gargantuan and unfathomable effort, but it's not pretty; it's harsh, weird, and frankly just misses the mark.
Constructive criticism:
* Please try using a consistent and STEADY beat. This beat does NOT compliment the tune. It is too fast paced compared to the tune and has an unpredictable nature to it. This is a weak point shared by many of Shnabubula's songs. * Less panning. * Less harsh sounds, preferrably none, the voice was not good and the high pitched stuff a 2:22 wasn't either. * More flow, basically pick your instruments ahead of time use them on and off or consistently throughout but don't switch from one to another in a totally random manner. * More natural tones rather than weirdly processed ones would be nice rather than the usual "wah wah"s on many of the instruments.
I apologize if any of this seems mean spirited.
