@Speed Gavroche: while I agree on some of those band types (like GNR and ACDC being ESTP), I must say that Rage Against The Machine is ENFJ, not ENFP; they're hardly concerned with discovery of new horizens, toying with concepts, or seeking novelty. They're more so focused on social justice and revolution, which is very focused on mass community ethics (or in this case, the fiery will of the oppressed masses). Also, Aux Ni is rather obvious; their lyrics scream of 'HEY! ALL THIS FUCKING BULLSHIT IS A SIGN THAT THE GOVERNMENT CONTROLS YOU, SO LETS FOLLOW A BETTER IDEAL AND REBEL!', and aggressive tert Se; 'Fuck you I won't do what you tell me!'.
They're also, by enneagram type, 1w2 > cp6w7 > 2w3(?) so/sp (or so/sx)
