I've been a fan of metal music all my life.
And I know what kind of messages it gives, especially black metal.
So I'm wondering if that's in line with our principles?

I don't think your taste in music has any bearing on the strength of your principles. It is a way of self-expression, of tuning into your emotions. Personally, as a teenager, black metal was my favorite genre because it had such heavy Satanic imagery.
My advice is to not take such things too deeply. Unless you think it has a negative impression on you, then by all means make a change.
Like it's been mentioned, don't overthink too much on the music you listen to.
As long as you don't notice any negative shift in your thoughts or emotions, enjoy yourself freely.
There is nothing wrong with listening to metal music. However, I know that there are bands, especially in this genre, that are disrespectful to Zeus and our Gods, so maybe it would be good to check the lyrics or the background of the artists in general.
Also remember that Gods can give you messages and signs through songs. I believe many of us have experienced this, so instead of depriving yourself of all this, you can focus on being more conscious and careful.
After all, music is beautiful and we should definitely have it in our lives.
