Metal seems such a huge genre with so many sub genres, so I can understand how someone might stick within metal.
I did that for hiphop about 5 years ago, it put me off music for like a year, as I got burnt out and bored

But I imagine metal could be doable.
These days I listen to Post rock, metal, electronic, ambient, idm, and a little modern classical stuff. I was almost 100% sure I would never listen to metal, back when I wasn't open minded with music. Now I love it
