I is possible to ad a streaming station as a playlist in MPD. Just create a file, e.g. /var/lib/mpd/playlists/20 Radio Toscana Classica.m3u with a single line:

https://nr12.newradio.it/stream/8744

mpc rescan
mpc listall
mpc add "The Rolling Stones - Jumpin' Jack Flash.mp3"
mpc find '(title == "Sabato")'
mpc findadd '(title == "Sabato")'
mpc playlist
mpc play
mpc current
mpc status

mpc lsplaylists
mpc load "RAI Radio 1"
mpc playlist
mpc play 4

mpc stop
mpc clear
