I have the following setup and working fine.
An example for one of them is as follows.
Create a new script and name it whatever you want.
For the Sequence,
Action Type → Play Media, select your device and hit + button. You can then select your station from the Radio Browser options.
Select the 3 dots, top right and Edit in YAML.

Copy the Thumbnail info, we’ll use this later on.
Save the Script.
In Home Assistant, Edit Dashboard and select a card, I chose the Picture Entity Card.
For the Entity, select your script.
For the image, paste the Thumbnail info.
Tap Action will be Toggle. SAVE.
You should have this. ![:crossed_fingers: :crossed_fingers:](https://community.home-assistant.io/images/emoji/twitter/crossed_fingers.png?v=12)
It’s just a matter of repeating these steps for however many more stations you wish to display.
