As titled. Got a group of friends that love to bash both teams music genre, A like screamo music and B like metal music. Obviously I'm on the A team, but I do listen to metal music sometimes as to gain knowledge on how they sound like but not that often until to the point that I need to listen to it everyday.

Team B were talking about how crappy and gay about the screamo bands high pitch vocals(some said like a girl singing) and screaming compare to their devilish metal vocals and screaming. AFAIK, all kinds of screaming methods are mainly from the vocal diaphragm box which needs you to tension it. It's just the matter of how you wanna sing it out. Btw, screamo music is also a mixture of metal and punk rock music... but not that heavy like those true metal band.

So any good tips and advice to stop this mellow problem?
