Radiooooo
Play a selection of songs from different countries from different eras.
#pouetRadio
Collects music posted to the Fediverse with the tags #tootRadio and #pouetRadio. Less a radio station really and just a list of Youtube embeds.
I've been trying a few dedicated Internet radio players too, here're some notes:
PyRadioLordzShadow/PyRadio
Don't like how it uses VLC to play the audio. Also not keen on how it looks.
PyRadiocoderholic/pyradio
Unrelated to the 'PyRadio' above, uses an ncurses interface, can use VLC, mpv, or Mplayer for playback. Probably easy to build a GUI for it if I really want.
Radio Tray NG - ebruck/radiotray-ng
I seem to have settled on this one. This, and are few other are inspired by http://radiotray.sourceforge.net/>the original Radio Tray. Puts an icon in your tray and you select channels from there. Comes with a program for customising the list if you don't wanna mess with json. I haven't tried thekvs/radiotray-lite, 'cause it wasn't in the AUR. They all use Gstreamer.
Shortwave / Kradio
If you like your Gnome / KDE ecosystems these seem to be your respective options.
As I mostly use MPD for listening to music, I should also mention you can add streams there.
