Want your favourite radio station like BBC https://www.bbc.co.uk/sounds/play/live:bbc_radio_one to load when your RasPi boots? Then this is a solution by editing the desktop boot config file
(Requires Raspios Desktop):
#nano /etc/xdg/lxsession/LXDE-pi/autostart
add
@chromium-browser --incognito https://www.bbc.co.uk/sounds/play/live:bbc_radio_one
or if you prefer Firefox (install that by #update #apt install firefox-esr)
@firefox-esr https://www.bbc.co.uk/sounds/play/live:bbc_radio_one
Note: the URL have to be in one complete line. No breaks!
