The ability to Request artist or Circles played more after listening to demo song

This idea is stemming off from another idea I had. It’s safe to assume that by now some of the GR library isn’t played all that much because of the rating program. I was thinking that after the song demos are added, there can be a button that request “play more of this artist/circle” if it has been shown to be played less frequently than other doujin and that will be added into the playlist. Or at least be considered more than previously. It’s just a way to help let other less known works get played

Example: I listen to a demo track and I want this to be played more but it really doesn’t appear much in the radio if at all. How do I ask for it to be played more if the only way to rate it is when it’s playinn?
