Benefits: venting bad emotions. This before the University of New South Wales, Australia, did a psychological test, the two groups of people separate, respectively, anger, a group of people listening to other music, a group of people listening to metal, and finally found that listening to metal of this group of people apparently a lot of anger down.
And we can also feel that listening to metal in our own lives can be very "invigorating"; it's good for some emotional regulation; and it increases the appreciation of music. Many metal fans, are very good at listening to the doorway, many even more or less master some instruments. Because most of the people listening to metal music does not just stay in the appreciation of singing; but more attention to the metal music in the guitar even repeated segment of the arrangement, the solo of the gorgeous, bassline smooth, and drums of the complex rhythm, so that will increase a person on the instrument to the arrangement of the appreciation of the ability to listen to a simple pop song, naturally appreciate it, which is just like you are able to appreciate the ballet, you can not appreciate into the square dance, because you can not appreciate into the square dance, because you can not appreciate into the square dance. It's like if you can appreciate ballet, you can't appreciate square dancing, because as the level of appreciation increases, you won't be able to find the part of square dancing that makes you feel excited; improve your cultural level, because, as we all know, the subject of metal is usually all-encompassing, and most often it's the portrayal of literature and history. For example, black metal has a lot of depictions of religion and nature, European folk metal covers a lot of history and national cultures, gothic metal creates a more ornate and gloomy yet beautiful state of mind, death metal such as Corpse contains a lot of medical terms in their lyrics (mistakenly), summoning creates huge visions with the theme of old Tor's Lord of the Rings, and lacrimosa is all coherent to create a tragedy of clowns and goddesses, eluveitie even transformed into a linguist, examining history to create songs like omnos in the long-lost Gaulish language, and even metallica, an extremely mainstream metal, still includes a lot of ancient myths and reflections on human nature.
