pretty captivating for a song of its structure.
I honestly have never played castlevania or heard this song, so i can not tell how remixed it is, all i can say is that it is pretty awesome
one flaw in it i find though, is the (is it a sytrus?) horn that comes in at 2:00 does not fit for a pretty simple reason once you know it
those horns and stuff have a very delayed attack, therefore the instrument will sound as if it is playing half a second late, messing up the beat completely, and once you are 2 minutes into a song, it is a bad idea to mess up the beat if it hasdnt been happening often before hand.
also i like the drum on the snare, its pretty subtle for how muc is there, i like it.
oh, and it is a symphony of the night remix?
usually right before the word remix, is the artists tag, so people might think this remix was done by someone named sotn
keep up the good work
