Listening to online radio stations under Linux

Method 1
Tuning into your favourite online radio stations without needing to open a dedicated music application is a breeze using RadioTray. The application runs directly from your system panel with a menu-only interface – thus making it very straightforward to use. Just don’t expect a fully featured bells-and-whistle jukebox for all RadioTray wants to do is give you access to your favourite radio stations with as few clicks as possible – a goal to which it admirably lives up to. Download RadioTray  

Method 2
I feel like a kid in a candy shop. I installed streamtuner today. Streamtuner makes thousands (no exaggeration) of internet music stations available to you. This includes all shoutcast and live365 stations. You also need to have xmms or beep-media-player or somesuch player that can play playlists. So: $sudo apt-get install streamtuner xmms and you are set! Now you can search or browse through the thousands of streams and pick the one you want to hear.
