metal is LOUD.. seriously, but still sounds very good, theres SOOO MANY different subgenres of metal its hard to follow at this point lmfao, but they all have their differences. Thrash is just... fast and aggressive to be honest, heavy metal is just glam rock but heavier to be honest lol, death metal is just hell in musical form, black metal is just ambient noise, loud bad guitars and norwegian guys going "AAAAAAAAAAAAHHHHHH I HATE LIFE" and then theres sludge which is just slow thrash metal lol, and doom is just sludge mixed with a little black metal. and funk metal is just....funky i love me some funky music.
