[mb-users] Recording>Work>Work chain

Hi,

if I enter a recording A of a song B that takes its lyrics from a poem 
C, I create recording A, works B (type song) and C (type poem). C points 
to an artist as its writer/lyricist, B points to a composer and to 
is-based-on C. A is-a-recording-of B.

Viewing a medium containing the recording A, I am nicely shown the 
composer but not the lyricist. In other words, the chain is chased one 
level, but not two. I'd really like the poem's author to be show. She 
would be, if she had directly collaborated with the composer...

A workaround would be to duplicate the lyricist relation in work B, but 
duplication and relationship clusters are frowned upon.

These are other examples of a similar is-based-on relation:

* Using the music of a song with different lyrics (derivative's lyricist 
should *replace* base's)
* Using the music of a song with additional/translated lyrics 
(derivative's lyricist should be *added* to base's)

Any thoughts?
