Lav it! X3
This is a buzzy's best song yet! XD
You've made wonderful use of FL Studio's default (predominantly osc3x based?) soundfont sets, loops and otherwise! Normally, when an artist uses the default sets with the program, they sound generic, or blend into other peoples work, but you've managed to execute this song beautifully without even a hint of triteness or unoriginality, but, in point of fact, just the opposite...
Your vision (a better word fails me) of this track is fresh and avant-garde... And never have I heard this pseudo-gameboy esque (more on that in a moment) sound work so well with an otherwise classical song, since, well I actually can't think of when.
Now a bit about the sound with disregard to the source material or context in which it's provided... At first, this track sounds like it's borrowing from the pseudo-gameboy genre (listen to kurenai-lightotaku for example), but at closer scrutiny, it somehow manages to avoid any genre, even that of gameboy music: which is a brilliant achievement in itself!
This track is genre defying, original, and it doesn't hurt that it's incredibly catchy either (I've listened to it about 10 times already).
My only dissenting comment is that I only wish it were longer, but that's just me. >w<
P.S. Lav you buzzy!
