Top 4 Metal bands

[Reinveil]

Narrowing it down to four is rough. I'll say:

Historical impact/relevance:

1.) Black Sabbath (in both Ozzy and Dio flavors)
2.) Iron Maiden
3.) Slayer
4.) Hellhammer/Celtic Frost

Personal favorites:

1.) Darkthrone
2.) Destroyer 666
3.) Midnight
4.) Summoning

[My name is Fez]

1. Tool
2. Opeth
3. Mastodon
4. Metallica
5. Black Sabbath

I know 4=/=5, but a lot of people argue about just how "metal" Tool is. So I figured I'd name a replacement in the even that you want to argue with me.
