re: Am i the only one who hates the growlers in metal?

Honestly for me it depends on what the song calls for. In power metal you just need those cheesy catchy cleans and in this case it’s the combination of this plus guitar lead work that defines that particular genre. In melodic and technical death metal often it’s the instrumentation that caries the melody of the song. Often in these genres the guitar work is so busy that adding clean vocals would take away the genre defining characteristic of the music. Not to mention that it would be difficult to find clean vocals that would “work” over such complex melodies and counterpoint. In black metal the maniacal high pitch screams are genre defining and similarly in melodic black metal it is often the guitars that carry the melody of the song.
