black sabbath does sound heavy try more of their songs than just what you hear on the radio.
and there is a whole lot more to sounding 'heavy' than playing fast or detuning your guitar.
heres is an edit to my post here.
bands like lamb of god, are death or goth or even devil metal
(pre black album)metallica megadeth bands like that are thrash or even speed metal
bands like bon jovi def lepard poisin dokken those are whats comicly called hair metal (names of all the hair back then)
bands like black sabbath judas priest and even deep purple to some extent are often called (by me atleast) classical metal. but yes you can hear alot of the older metal on classical rock stations.
now as you can see your insult calling what most here listen to "not metal" is completely false jamesplayer. nearly every band that was once called metal can still be called metal execpt a few. post black album metallica became pop music for instance. named so because it is what is popular.
me personally i would like an apology from you jamesplayer. but ill settle for you simply learning from your mistake.
They say the END is near, but I'm Tired of waiting.
