Well, I were watching some MUGEN videos, and I dropped by this.

What's the background music in this?

I were looking at the comments and it says something about Einhander, but I did looked at the Einhander music at HG, but I didn't find it.

Can someone tell from what videogame is that BGM(Also the name of the track)?
(BTW, MUGEN is a fighting game where you chose your own fighters, stages,BGM, etc)
