Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.

All that stuff about heavy metal and hard rock, I don't subscribe to any of that. It's all just music. I mean, the heavy metal from the Seventies sounds nothing like the stuff from the Eighties, and that sounds nothing like the stuff from the Nineties. Who's to say what is and isn't a certain type of music?
