But that isn't what this thread is about.
Metal is music anyway, since any kind of arranged sounds into patterns is considered music.
'Arranged sounds into patterns'- that's your experience of music. Sorry lady, but that seem as some kind of robotic thinking. Maybe you are young, maybe you are bombarded by media and internet, but that's not the holy grail of music. Music is singing of your soul, language of your heart, broken, shattered, or cured, whatever.
