No album songs on Spotify radio playlists?

[Flower4]

I see no songs of my album on my Spotify radio playlist, just the singles. I also don't have my songs on any similar or related artist radio playlist, while others that are on playlists I'm on have. Is that a bad sign? Just a few listeners/streams from radio playlists and many from regular playlists, etc. Is there anything I can do to have more of my songs on other radio playlists (of others)? Thanks.
