No it doesnt. Look at bands such as Metallica, megadeth 或者 anthrax 或者 even powerwolf 或者 WOLF. Wait?.... What is a Justin bieber 粉丝 doing in the metal club? Im just wondering, I'm not a troll
金属乐队 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 羊肉, 羔羊 of god 或者 burn the priest 或者 cannibal corpse the are death/black metal so its just only screaming singing
