Metadata is the domain of the encoder.

Opus metadata is fully supported. For FLAC metadata may not be displayed
on the status page but is still passed to the listener.

That is *ONLY* for ICY (read: MP3 and AAC) streams as MP3 (and AAC) do
not support metadata.

However for every non-legacy formats such as all Ogg-based, all
Matroska-based, and FLAC metadata is supported by the format itself.
Icecast will happily relay any metadata updates send by the encoder.

Yes. Set the metadata in your encoder. See it's documentation on how to
do that.
