Exactly this separation is the point. That separation is what ICY is about. MP3
does not support metadata so a side channel is needed as a workaround.
Icecast does provide this just fine if asked for it.

And again, there is nothing to do on the Icecast side. Let me make this
clear: Icecast's listener protocol handling code does not even know if the
client is connected via TLS or not.
I don't want to point here at VLC. Also keeping in mind that others behave
the same way. I just want to make clear that there is nothing we can do on the
Icecast side as there is no problem on the Icecast side.
With best regards,
