If you consider ID3 in a live ShoutCAST/Icecast context it looks more like
timed metadata because the artist & track information changes throughout the
lifetime of the presentation. The tags definitely only apply to certain parts
of the timeline in that context. 

Another way to look at this is to view it like metadata in chained Ogg files.
The info at the beginning definitely does not apply to the whole file.
