This script will play radio and should work on macs and linux computers if you have VLC installed. Better than iTunes, in that it works with more stations, and doesn't clutter your media list.

# source: http://gist.github.com/210643

# Plays various radio channels, using VLC. Run me from a terminal to see radio station options.

# If your radio skips a lot, you need to suid 'renice'. If you don't know what that means, don't try it yourself; it has serious security implications.

# For this to work, you need VLC. On debian / ubuntu: apt-get install vnc
# on macs, download VLC and install in /Applications, from here: http://www.videolan.org/vlc/download-macosx.html
# uncomment the next line if this script can't find your VLC, and point it to the vlc binary.
