i like some non metal artists here and there, but everything that i listen to in regular rotation is metal.
i'm really picky about what i like, so i don't have a lot of variety in said rotation =/
This is the problem. There are a few artists I REALLY like in metal and will always love the genre for that. However, when I started expanding my interests because of that and started listening to some other genres (especially electronic in my case) I was overwhelmed by how many artists I liked. I can't stand stagnation, so metal has taken the back seat in my playlists.
I will say though that the bigger offshoots of metal have taken my interests lately, mainly post-rock/metal, instrumental and sludge/doom/stoner bands. The more iconic forms of metal have some slim pickins these days.
