hitradio Ö3

works perfect in Chromium on a RPi. No additional plug-in needed like the browser does. You can even close the browser and the app will still go on. I also installed it in Chrome on my Mac and it works perfect. If I close the browser by accident the music will still go on. I also like the pop-ups of the next/current song. (Would be great to have a feature to disable this thou at times.)
