Why hasn't anybody featured this on a game yet!?
This is amazingly well written and it fits the mood for an intense battle easily.
And it's one of the first Google results on "True Final Boss"!
One cannot get any more lazy than that.

Awesome song!

This is exactly a tune that fits for a final final boss. It's a bit unfortunate about the silent 23 seconds after the song finishes.
Maybe you could make it up with a song for the final final final boss?

How the heck does this have such a low rating?

It's awesome, for god's sake!

Speedy

I would love to see this used as a boss track. Sounds like a boss track for a Sonic or Touhou game as well. Considering how fast paced both game series are.

The synth sounds very cool and quick. The drums are very good here as well. I liked the bass line as well. However I like how furiously fast this tune is going. The guitar sounds really awesome, would have been cool if you had added a breakdown on the guitar for effect, it would be right when you think you won but the boss goes to phase two.

Overall, this is pretty beastly, nice work!!
