On my phone, I have these radio apps;
RAI3
BR-Klassik
Radio France
WDR
rbb Kultur
NDR Kultur
A legal ruling a couple of years back meant that Bluesound is not able to offer radio stations outside a user's country within their native app, but all of the above can be cast to the Bluesound Node (whereas other radio apps such as SWR2 don't permit this). In terms of quality, most radio stations are still engaging in the loudness wars, with only BBC R3 and BR-Klassik seeming to offer appreciably better quality. (If you know different, please let me know!). It would be great if RAI3 and France Musique could improve their streaming quality, as their content deserves it.
