This sounds like an Ogg thing rather than a codec specific thing, so
I've trimmed
all but ogg-dev.

This looks like going back to Amiga modules, woohoo :)

In any case, if it's merely supplying several tracks and leaving the
mixing to the
user/player, then nothing's needed for Vorbis (or FLAC, or others). Ogg
allows
several tracks to be concurently multiplexed, so players can mix them. A player
might then decide to let the user tweak volumes of each track, but
that's outside
the purview of Ogg. Something that could be added, however, to make it easier
on the player to *know* such tracks are supposed to be handled that way, are
standardized message headers to Skeleton to indicate such tracks.

There is, though fancy karaoke type overlay is still work in progress:
