The info is absolutely correct from the server point of view. At that
point in time the server is already sending the next song to clients.
Why you hear something different is because your listening client has a
significantly sized cache to avoid buffer underruns (which is mostly a

Then polling the server for current playing song is unsuitable for you.
You'll have to find a player that reads the metadata from the stream AND
does it in sync with the buffer. If it doesn't do the latter, you'll
still face the same problem.
I'd try out browser playback. Works very well for ogg/vorbis and should
also start working for opus streams on most browsers now.
Please note, that just adding 'delay' to presenting metadata is NOT a
viable solution, as the buffer size may differ and also clients fall
behind differently and there might commonly be a delay of anywhere from
2 to 60s.
