If the band members did not practice and make sure their music came in perfect harmony then yea it might as well be a bunch of silverware being thrown out on the floor.
According to the National Association for Musical Education, they say " He or she is able to perform music in a manner that illustrates careful preparation and reflects an understanding and interpretation of the selection." As far as i can tell I am sure metal bands follow those guidelines.
Another debate is whether or not heavy metal music is a corruption to the listeners mind and offers no benefits to the fans. Again, i argue that the music itself and the community it offers can actually befit the listeners on a personal level and even an academic level.
One of the biggest benefits of heavy metal music is it can be a release for those who have stress, depression or anger issues. In a article titled " Extreme Metal Music and Anger Processing " there was an experiment done where they would have fans of heavy metal make themselves mad and then chose a metal song of their choice. Once they started listening to the song of their choice they notice their heart rate went back to normal. This shows how the music can be beneficial to someone on a personal level.
Also if you are feeling slow or lack motivation, heavy metal can most definitely help with getting your adrenaline going. whether its to help you stay up to write a paper or just trying to get that extra pump at the gym
Another misconception is that people who listen to any heavy metal music is that they are senseless morons that just bang their heads. I would like to argue that heavy metal music can actually benefit people on a academic level. One example is that the music can actually make the listeners think more. With the vast variety of songs one can spark ones interest and have them research even further into the subject.
Another way i argue that heavy metal music can help on an academic level is its a lot like reading a book but more intense. In order for the listener to get the best experience of the music they must analyses the music carefully which makes them think more.
