I added 8 songs from discover weekly that I liked into a playlist and attempted to start playlist radio. What I got was "Radio station error. We can't load this radio station right now. Please try later." This is on my Android. On desktop I also can't start playlist radio, I get a message: "This radio station cannot be started. Please try with something else." Note that this is only for that particular playlist. My other playlists are able to start playlist radio.
I have tried radio for this specific playlist and another official playlist "Fresh EDM" and all my devices yield an error. I have tried on Android Lollipop, iphone 6, and windows desktop. Is it because my playlist contains a little-known track?
