@bdiederik@lx snapcast is designed for LAN streaming to multiple speakers or groups of speakers in sync. It also requires a music source like Navidrome writing to a fifo file. Not what I'd recommend here
@bdiederik@lx the other disqualifer for me is that I prefer to download my music for offline playback and then sync over WiFi because I pay for data usage. I understand many have unlimited data though. This is another reason I use Subsonic clients (DSub primarily, looking Tempo lately).
