Well, you'd use id3info, because the id3v2 tag is not guaranteed to be
a particular length and may also contain binary information. But,
correct tool aside, the more relevant point is this information is not
actually available to a player that is playing this as an input stream
until the complete stream has been received. If you want to do that
you have to cheat and cache everything before you start playback. Or,
in more general terms, doing anything non-linear with multimedia
information is very difficult to handle in a streamed manner.
