If you want to use the command line interface to listen to your favorite radio online, you can use the mpv software, which allows you to play any mp3 stream without any graphical interface:

mpv http://icecast.radiofrance.fr/franceculture-midfi.mp3

There are different sites that list the urls of the feeds, for example : https://www.hendrikjansen.nl/henk/streaming4.html
