This is a list of styles and genres of Heavy Metal, Rock, Punk Rock, and Blues
In case you were wondering how many there are, I came up with 547 different styles and genres.
Yes, I know that some styles don't exactly fit in, but if it has even the slightest connection to rock or related genres or musical movements, then it's included.
