Venom, the band that quite possibly changed heavy metal music more than other band, definitely deserves to be in this game. Really, they created the entire extreme metal genre by themselves practically and to see at least one song from them would be awesome.
If I were to choose a three-song pack of Venom song, I would go with:
"To Hell and Back" (awesome guitar solo)
"Schizoid" (can't find any links to the song. You'll just have to buy it. It's amazing)
If we're going to go all out and possibly get a full album, I think that the whole Black Metal album would be ****ing badass.
Who else supports some Venom?
