Charles,

thank you for your precise quoting!

You are right, but let me add some remarks on the proposed tag set (below).

One problem are multi-CD albums: Tracks on the CD always start a 1, while booklets 
sometimes continue counting. If you use the track numbers as stored on CD, you 
have (at least) playing conflicts: Most players would play track 1 from every CD, 
then track 2, ...
For the date a more formalized syntax would be helpful (assuming some software is 
expected to sort tracks by date). E.g. some ISO standard.
In addition to the ISRC the MCN (Media Catalog Number) can also be extracted from 
CDs. Would be helpful if someone actually wants to buy the CD (IMHO).

Having multiple PERFORMER tags was a big disappointment with my player: Either id 
did display nothing at all, or it displayed only one instance of those tags. So I 
invented my own meta-syntax, that goes like this (JFYI):

performer1, performer2, ...: instrument1, instrument2, ...; performer3: 
instrument3; ....

Up to some limit this works for every player. When listing 40 performers or so, 
you have a problem however (I know one CD where 40 singers were listed together 
with their recording position and voice)
