i can sort of agree... to a point.
besides soul, i have a huge collection of hardcore, grindcore, black metal, crust and related stuff (think bands like 'kiss it goodbye', 'born against', 'man is the bastard', 'torches to rome', 'antioch arrow', 'second story window', 'wounded knee', 'blown-apart bastards', 'luzifers mob', etc). i'm sure most folks on here would find this stuff un-listenable, but it is undeniably very primal and emotive music, but not really 'soul'.
