I like many pagan bands such as Temnozor, Cruachan, Arkona, and Ensiferum. I do not allow any of these bands to influence my beliefs; I simply like them for their atmosphere and folk melodies.
I’m not sure if it is sinful in and of itself.
But I do think that your questioning of this is leading you to a deeper life with Christ. He is calling on you to carefully discern your music-listening habits.
I’m not familiar with these bands, but in general, I would not think that listening to pagan-themed music would be much different to listening to secular-themed music or music from another culture, which may necessarily be pagan.

I don’t think bad taste is necessarily a sin.
When I saw the title about Pagan-themed music, I was thinking like Der Ring des Nibelungen and so forth.
