The board works with a range of online services including Spotify, Deezer, Amazon Music, TuneIn, Tidal, Qobuz, Napster, iHeartRadio, QQ Music, QQFM, but you can also play audio from local storage in your mobile phone or a NAS thanks to Foobar2000 or other programs with UPnP or DLNA supports for Mac or Windows PC.
