Let users choose language/country for the playlists and announcements. I live in Spain and so get all advertising just in spanish (and so dont understand a word which also makes the advertisments useless), get only spanish playlists and podcasts. Was the reason to cancel my subscription as its useless if I can only get content I do not understand. When choosing a playlist I often have to guess what its even about as I cant understand the titles and description.
