The best kind of music ever made. Created as a branch of rock, jazz and blues.
People stereotype it to death, saying it's nothing but loud guitars and screaming. Most of it is actually composed of complex riffs, excellent solo's, and the best singing in the music business. Sure, there are a few black sheep's in the genre but when you ignore that stuff, you will see that it is awesome.
Listened to by metalheads, who are also stereotyped. Close-minded people think that metalheads are nothing but loud and obnoxious rejects. This is usually untrue, a vast majority of metalheads are deep thinkers and individuals who don't just follow the crowd.
Some examples of good metal bands are
Lamb of God
Avenged Sevenfold (before their self-titled album)
System of a Down (although their genre can be disputed)
Examples of metal stereotyping
