When working from home, due to COVID-19, you do have the luxury of listening to music of your own choice. And it doesn’t have to be via paid services like last.fm or Spotify. No, you can use good old fashioned internet radios as well. And there is plenty out there!
A good place to look for stations is: Radio Browser.
You can use URLs from that website in your favorite application, like RhythmBox on your desktop computer or RadioDroid on your smartphone.
