Re: Multi-channel labels in Vorbis comments

Oops, meant to reply to this all earlier...

The RockBand/GuitarHero franchises are using massively multitrack ogg
files (.mogg) that are similar to the proposed use case.  I hadn't
looked at them to see if they were a general purpose solution or were
just hard-wired arrangements for specific games.

I did use one to make my own mix of 'Still alive' though :-)
