No it doesnt. Look at bands such as Metallica, megadeth या anthrax या even powerwolf या WOLF. Wait?.... What is a Justin bieber प्रशंसक doing in the metal club? Im just wondering, I'm not a troll
मेटालिका is heavy but has no screaming but u look at bands like system of a down and slipknot they r a bit of both screaming and heavy with no screaming but than u look at a band like मेमना, भेड़ का बच्चा of god या burn the priest या cannibal corpse the are death/black metal so its just only screaming singing
