^Some of those are not metal but I'll leave it to others to point them out.
So you like trad metal and thrash. Cool, me too. But I also like death, stoner, doom, progressive and some symphonic. Part of what helped in developing my taste was exploring the various subgenres of Thrash. Death/Thrash, tech thrash etc. And you can develop a taste for doom by delving further into traditional metal. Then eventually you might find yourself enjoying harsh vocals like i do.
