With music made by nazis it very much is.
You stream it: you are paying nazis, you buy it: you are paying nazis, you listen to it after you know it’s nazi propaganda: you are willfully consuming nazi propaganda as entertainment (unless it’s research into hate speech).
The idea of the music was to signal a specific political alignment with the ideas expressed.
Well, the good part is that they tell you. Also the nazis can’t help but be nazis pretty much in all aspects of their lives.
