And no self respecting rock fan would call those bands metal.The Plunk said:"You like metal? Do you like Nirvana/Green Day/Slipknot/[other shitty mainstream rockband that no self-respecting metal head would ever refer to as "metal"]"
The same for AC/DC.
Edit: Also, slipknot isn't music. It's noise with people talking about emo BS that vaguely resembles a tune if the tune was wrung through an industrial drier and then used to strain tea.
