Not saying it does not exist, but as someone who has a bit of a diverse cultural origins and listens to music in at least 5 different languages, the Roon layer becomes much thinner when this is not Anglo-Saxon music. Not saying it does not exist - French, Spanish, Portugese (+ Brazil) music is supported let’s say for the more famous names. Go beyond the top names and support goes down dramatically. No lyrics (Deezer I feel does a bit better in their lyrics feature), no bios no album info, no pictures.
When I go to music in Hebrew (and I know of quite a few Roon subscribers in Israel), this is becoming almost zero. I wonder what the situation in Oriental languages. I can imagine there are underlying content providers who simply do not support these languages, but I hope something can be done about this!
