Airtime is a free open source radio management application. The Airtime server runs on Linux, but the interface can be used from anywhere, using a web browser.
It features DJ management, playlists and shows, SoundCloud integration, supports Icecast and SHOUTcast and comes with a jQuery-based interface that supports drag and drop.
Airtime 2.0 has been released a few days ago and it includes many improvements like easier Icecast and SHOUTcast streams configuration, better calendar, playlists and SoundCloud integratoin and more.
In Airtime 2.0, Icecast and SHOUTcast streams as well as the hardware output API (ALSA, OSS, AO, Pulseaudio, and Portaudio) can be configued through the web interface. Also, you can now have up to three streams with different bitrates and point them to different Icecast / SHOUTcast servers.
Radio Tray is a minimalistic radio player for Linux that runs in the systray (can also use an AppIndicator for Ubuntu). The application is very lightweight and straightforward to use and comes with notifications support, multimedia keys and a sleep timer.
A new RadioTray version was recently released with plugins support so if you're a Python developer, you can now easily create new RadioTray plugins (my only wish is a last.fm scrobbling plugin).
The new version also comes with read-only bookmark support, improved user interaction in bookmarks configuration dialog, moved various features to plugins (sleep timer, notifications, media shortcuts), a new history plugin and bug fixes.
