Well, then I have something for you... at least for the more metal head types out there... I was sifting through my vocaloid collection earlier today, and I found a certain song... This song sparked a ridiculous journey across the internet trying to find the original author, then trying to find what else he's done, then trying to find where it's available... To say the least, I spent the better majority of my night finding this stuff... and now I'm gonna be nice and share it with you.

First off, here's the song that sparked my interest:

I heard this song for the first time while I was playing Beat Hazard, an indie game available on steam, basically a top down shooter where the enemies movements and patterns, along with your weapon strength are heavily influenced by the intensity of the music... It's a fun game, you should check it out.
Anyways, I was playing survival mode, and this song showed up about 20 min in, and it blew me away... Literally... I died shortly after the song started. So I looked it up in my itunes playlist and gave it a full listen... freakin' amazing is all I can say.

And for those that aren't fans of vocaloids... no worries, this guy has an album (Or two?) out featuring various human singers as well.

Example:

For those that like what you're seeing, I shall now reveal the man behind all this music:
Yuyoyuppe
This isn't a link to his official page (Assuming he has one, if he does, I couldn't find it), but it does give a list of most of the songs he has done for those that want more. And if you care to, you can search him on google if you really want to find more about him.

Enjoy! I know I had multiple eargasms when I heard this stuff, hope you do too!
