The MaidenFans Band did a good job for Alexander The Great. Best cover of it, for sure. It gets my vote (or not, because I'm late, but w/e), because Disbelief has shit drum sound, shit guitar sound and shit vocals. Good idea though.
Primal Fear's cover brings nothing new at all. It's decent, but still... Same can be said for Nocturnal Rites, except it has bad vocals.
Innerwish is just a rehash with shit vocals.
Steve 'N' Seagulls cover is awesome, love genre bending covers like this. You should've had this one in the game too:
Solitude Aeturnus cover is cool, but brings nothing new.
Anaal Nathrakh's cover is genius, as is the person who nominated it

Retains the riffs and melodies but in a totally original package. Totally sounds like an original Anaal Nathrakh song. Y'all will see this once their album I nominated for G-MAC appears in that game.
