where can I find MIDI files?(and also specific)

I'd love to have MIDI files for the songs from DevilDriver, Dimmu Borgir, Behemoth, etc metal bands ...

anyone know where they can be found?
btw GOOGLE IS DRUNKEN MASTER, and I dont drink :/
I imagine some of you guys here must know of something.

I didnt find anything useful while searching the search engine in these forums, so I figure its easier to just ask you here.

You can go to Ultimate Guitar (or other site) , download some guitar pro tabs and convert them to midi.
