Hmm, I had that link at one time and lost it, thanks.

Well, whining I can handle, but this is the reason I'm talking
about the metadata (not the Vorbis comment header) and standard
rdf type ways of presenting it.

That would have been the sensible thing to do.  You've removed
the preceding sentence about headaches trying to be consistent.
Things like my example are the motivation for trying to find a
working set of rules.

I used to do that a lot more than I do now.  I used to use winamp
(back in the bad old days of windows) to enter all this information
in as a comment.  It's human readable, but reduces the potential
uses of the information.

That does seem to be the best use of ARTIST & TITLE.

It occurred to me that rock, pop, blues etc. people typically
want the performer, classical (inc. opera) you'll likely want
to see the composer.  I haven't listened to enough jazz to
know what should be done there.  Not a solution, just a rule
for existing data; it's a player issue anyway.
