Unable to capture streaming data from Rythmbox or Shortwave

Screenshot attached. If I am playing a streaming radio station via Shortwave or Rhythmbox and run songfetch, I get the error attached. If I stop playing music and run songfetch, it sees Artist as the radio identifier and the correct URL.

You can see in this screenshot the pulseaudio app (clicking the volume icon in the Waybar) shows the app playing the song, the artist and song title, songfetch throws error.
