ID3 tags don't apply to streams, although a source client may use ID3
tags to insert song information into the stream.

The song info that you are referring to for mp3 works by inserting 1 or
more bytes every so often in the stream, effectively breaking the mp3
spec.  Because the spec gets broken, it's upto the client to inform
icecast that it can handle it.  It looks like media player doesn't, and
the likes xmms and winamp can disable it via check boxes.

It's a general issue for mp3, not really a problem though, the mp3 spec
just didn't allow for it.
