Owntone has my library to play in my house through shairpoint-sync driven amps & speakers in different rooms. (Synced perfectly and seamlessly - your ears can really tell too).

That same Owntone installation over wireguard using http stream in my phone/laptop browser when I'm not home.

Owntone & airplay2 is absolutely first rate.

Owntone http streaming is plenty good enough for me.

(Owntone also works great with your spotify subscription if you do that).
