I'm in Israel but originally from Russia and listen to some Russian music and Spotify somehow assume Polish would be just as good for me. Leave alone decent amount of German music due to Rammstein.
I also got some Scandinavian stuff too but it usually fits my taste at least.
What region is your Spotify set to? It seems to base the recommendations on the region (I live in the Nordics, but used the US version for some time and got recommended a ton of spanish music).
