Internet radio brodcast software.

[Eurofighter]

I am new to Linux although I have used it at work I now have a spare pc and want to install ubuntu. My Internet connection isn't really good enough for a big plex server where I could allow my family and friends to watch movies. But what about Internet radio. I have a lot of friends in the music industry so would be able to make content with them but I need to get the radio station made first.

Does anyone know the best software for a radio station?
