I live in Spain, so it suggests Spanish podcasts to me, even though I only listen to podcasts in English or Catalan.
Music the same, I mostly listen to music in either Catalan or English, with a couple of Spanish songs in my lists. But lots of his suggestions are for music in Spanish. Heck, I just see that one of his recommendations is new things in Flamenco, even though it's a musical genre I haven't listened a single song of (nothing against it per se, only that I don't like it).
As I'm using it more to listen to podcasts now I find it hard to listen to music, because if I leave a podcast mid reproduction and play some music I have to remember which podcast it was, search for it, and then I can listen to the rest. Two separate modes, one for music, one for podcasts, would be good. Maybe a mixed one for people who do both mixed.
I will not add on how most of the music it suggests (when not suggesting things that I like) are things I already have in my lists, not good things that I could add to them.
It needs some work.
