I disagree.
I like SOME of System of a Down's stuff.
And I like a small handful of Metallica's work.
I know more of Soad's work, though, so I can speak more for that aspect.
Anyway...
I respect Metallica as a band... I just don't necessarily like all of their music.
And since they covered Misfits, I've respected them a little less.
I don't think they should have, to be quite honest.
