Hmm well I'll have a go at this as well using the broader genres as my guidelines
I'd have put nu-metal in this slot but don't believe it to be a legit metal sub-genre. So Industrial then. Yeah I care for practically none of what I've heard beyond Strapping Young Lad.
9. Progressive Metal
I started out with a bit of a taste for Prog but as time has passed it's really become quite uninteresting for me. Queensryche aside Future's End are the only pure prog band I still like.
8. Folk Metal
Again I had a bit of a taste for folk metal early on. Nowadays not so much but I do still enjoy enough bands, Orphaned Land in particular.
7. Power Metal
I like a few more power metal bands then the previous genres here. Blind Guardian, Nevermore, Persuader, to name a few.
6. Thrash Metal
Close run between thrash and power metal since my interest in thrash is waning significantly. For a bit of fun I still get into it but no longer have much drive to explore the genre.
5. Heavy Metal
I'm including the NWOBHM here because it is very much heavy metal. Sabbath, Priest, Maiden, Saxon, Accept, UFO, Mötorhead, Angel Witch, damn too many more to name.
4. Viking Metal
I don't have as much knowledge here but I love literally all the viking metal I've heard so far.
3. Black Metal
Can't get enough BM honestly. First and Second wave offer so much.
2. Death Metal
Yep if you know me now this is no surprise. The classic DM sound does so much for me. Some melodic death metal and tech-death also works wonders as does a bit of progressive death metal. Astonishing to think it wasn't six years ago I couldn't stand the genre.
1. Doom Metal
From the moment I started exploring the genre it became my favourite. I adore doom. The emotion it evokes, the atmosphere, the crushing riffs, the variety. So much to offer. Traditional doom, Sludge, Doom/Death, Black/Doom, Funeral Doom I can't get enough.
