Radio Tray is an online radio streaming player with a minimal interface that allows you to listen to online radio stations. This is not a replacement for your media player, it’s an applet that sits on the top panel and allows you to quickly switch between your favorite stations – read more about it on the Radio Tray project page. However, Radio Tray is not working in Elementary Freya after final release.
To install it open a Terminal and paste the following command:
sudo apt-get install radiotray
Radio Tray is not working? Let’s fix it
By default in SysTray.py there is a call to gtk.gdk.
sudo nano SysTray.py
Then press Ctrl+W to search for gtk.gdk.threads_init() and add a # in front of it to comment it.
Now press Ctrl+O to save the changes (WriteOut), leave the File Name Write as it is and hit Enter. Press Ctrl+X to close the file and now you can enjoy Radio Tray.
An alternative for Radio Tray you can use Great Little Radio Player, which has a smart looking GUI and over 500 radio stations of different genres from different countries.
