You’ve come across a temporary issue in Roon servers whereby geo-restricted streams are incorrectly blocked to everybody. I’ve taken off the flag for now on both Magic stations. Try now.
As for Boom, for a similar reason, I can’t add any stations to the database at the moment. However, you can add to my live radio, so add https://listen-boomradio.sharp-stream.com/65_boom_radio_live_128 to your stations. You will need to give it a name, but should work OK.
