What do different rock styles represent?

It doesn't make any sense. Many of them were added by music critics.

1 When I started listening, I was also hungry for genre. I seem to know more, so I went to those bands to listen to what style I liked at that time.

It turned out to be very narrow.

The styles of many bands are not the same. For example, tiamat's early music is more about death, and they are also gothic and lyrical.

Many bands may have folk songs and metals in an album.

Now is a diversified era, both playing pop rock and many musical elements, such as funk and hip-hop blues. ...

2 on the music style and lyrics positioning and other issues

For example, Eluveitie is generally called pagan metal, also called pagan black rumor metal. Their band is really heavy, but they have joined many national instruments, such as Irish bagpipes, whistles, drums and harpsichords. At this point, they have integrated their own ideas and formed their own style.

They learn from Celtic culture to make music, but music flows in culture and is reflected in lyrics. Hervey's music, known as Celtic, is deeply influenced by traditional Brittany, which is also because there are few Celtics left in their country. Many bands pay attention to a certain culture in the expression of words, but have little connection with it in the arrangement. So hearing Scandinavian metal, for example, does not mean that its music arrangement is very ethnic.

Tell a joke, really.

I saw someone posting in a forum asking about the XX band. Are you XXX?

Then the band replied, we don't know what style we are. Who told you that? Ask him ~
