That is not a trick, that is Flash ActionScript by the looks of it.
Flash (and by proxy it's scripting) is pretty much deprecated now.
And if you are suggesting presenting id3 metadata then I'd rather not
see that, the web developer do not need to know if it's a mp3 ID3 tag or
Ogg metadata, they only need key value pairs. And the mp3 stream parsing
code can re-map the most common id3 tags to a more sensible (UTF8/UTF16)
lowercase key name, it's possible even some of the Ogg tags may need
People at Hydrogen audio have tried to remap these into something common
That is probably the most comprehensive re-mapping guide on the web
Using Vorbis Comments as the basis seems sensible (only lowercase

Audio meta tags should be applicable to the webplayer ( one file vs.
multiple files ).
I doubt anyone streams their ringtone from the web.

in our present days there is a growing demand for streaming by

I do not see why this is an issue, as long as metadata can be handled,
like for example meta data in ogg (files and live streams). Then any
metadata can be added.
Are you suggesting that the default audio and video player presents a
info via the UI?
I can see artist (creator) and title, year, copyright/license (for
example "CC BY") as the 4 minimum pieces of info that would be useful.
And would work for audio and video.
But for custom UIs or enhanced UIs the webdeveloper would (or at least
ideally should) be able to pull any metadata from the file/stream and be
notified if a stream changes/send new metadata.

I fail to see what this has to do with metadata. And if you are
suggesting any playback length limiting for audio that is not "licensed"
then that is not a discussion I wish to be part of as that would be akin
to censorship. As a independent artist myself I'm not registered with
any PROs nor do I ever have the intention to do so which would mean my
own music would be limited to 5 sec playback.
I suspect that you are addressing the wrong group here for most of the
stuff you are talking about. Any playback length limitations due to
potentially legal issues is the responsibility of the party that
actually shares the audio or video, not that of the browser developers
nor the web standards.
If you want certain metadata tags standardized then please know that
none really exists of id3. Not even Ogg (Vorbis comments) is "standard".
But a few semi-official ones are found here
(these are also listed on the Hydrogen Audio wiki page)
Also note that Vorbis comment keys should be treated as case insensitive
so Vorbis comment keys could easily be used as is with no re-mapping
just a case conversion.
And I'm sure Xiph and Hydrogen Audio would be happy to help
"standardize" various key names for tags and the tag formatting as well.
This could be as simple as WHATWG creating a table of the most
important/common keys used. And then the Hydrogen Audio wiki would
replicate that table and add the mapping advisory between WHATWG and
Xiph could update their page on Vorbis comments to match/include the
WHATWG key names if they are not already listed.
I have no idea who maintains http://id3.org/ but I'm sure they would
want to participate too.
