Yep, and OPUS files are even lighter. That's why I just sync a "currently listening" music folder with Syncthing and do not think about connection, caching and all that. (I have the rest reachable when I need it, of course.)
200ms and even n+1 won't cut it for a subway, a semi-basement pub, a tunnel, a train or an airplane trip, a hike, a countryside visit, etc.
