No, I am not calling down an imprecation on radio technology. Rather, I want to highlight a great free software streaming radio system that uses a Curses-based interface:

Curseradio allows you to browse streaming radio stations listed in the opml.radiotime.com index. There is a large listing, and no proprietary software is required to view or to listen to the stations. Use arrow keys to select a station, “enter key” to start streaming, the “q” key to quit, and “k” to stop the streaming without quitting (i.e., pause).
In Guix, the command is “guix package -i curseradio” to install it. Note that a few days ago I had Guix fix a bug that was preventing the streaming from starting (a command path issue) so you may need to update your Guix channel, or cherry-pick Guix commit 8d8c6bf.
