TuneIn is a great free service that allows you to tune in to thousands of radios around the world.
Their service allows you to listen on iOS, Android, Alexa, Google Home, Roku, TV's and more.
If your device / speaker isn't supported, you can use AirPlay & Google Cast to stream from your mobile device.
You do not need a premium subscription / the pro app to listen to GGRadio via TuneIn, the app will instead play advertisements infrequently to you - these do not support GGRadio.
