Spotify "Radio" feature just tends to want to give me music I've already listened to over new music. Whatever algorithm they are using has waaaay overfit to what I have already liked.
There used to be curated playlists done by humans, now almost everything is "made for you by Spotify" playlists which, have the exact same issue as the radio stations, suddenly it's all the same music you've already been listening to, very little new music. If you want new music, you need to find a playlist made by a user instead.
