I've been thinking about that too. I think the current convention is to
give the filename a special name. That also makes sense. But that means
you can "detach" 2 such files in the same directory...

Yes, these all look like valid possibilities. IMO we should all merge
them into 1 tag that could be SLEEVE_TYPE. That would be a number like :
* -1 front cover
* -2 back cover
* -3 inside CD (on transparent CDs)
* 0 page 0 of the booklet (if different than the front cover)
* 1 page 1 of the booklet
* . etc

Well, for the lyrics or transcripts it makes more sense to have it muxed
with the stream. But I understand it takes more time to have it authored
this way. In the other hand, I don't think it needs a special treatment.
Or maybe for lyrics, that could be displayed a special way in a nice
audio player... But then that would mean the format of the lyrics should
be in a given format (plain text ? HTML ? XML ? other ?). So I'm not
sure we need to define that now. But if someone comes with a good
solution, that could be nice.

You can look at such an example here :
One CD is named "Housemusic" and the other is named "Electronicbody".
