nested nodereferences

Issue Summary

Hello,
I have a site with the following structure of node types:
Artist
Album (with nodereference to Artist)
Song (with nodereference to Album)
Lyric (with nodereference to Song, could possibly change this to also have nodereference to Album and Artist)

I'm trying to find a module to best allow users who don't want to add four separate nodes (artist, album, song, lyric) to be able to just add a Lyric node and from within that node choose the appropriate Song, Album, and Artist. This module seems to be the closest match so far, but is there any way it can support this nested kind of content type / nodereference situation?
Artist
-Album
--Song
---Lyric
I think an issue is that Song names could be the same, and so could Album names, so loading nodereferenced nodes and nodereferenced nodes of nodereferenced nodes might be needed. I understand this might be way outside the scope of your module, but it's a use case I would appreciate advice/help with and may be something interesting to consider when developing further.

Can nodes that pop-up and which themselves have nodereferences trigger a second pop-up and a third until the top level (highest referenced node type) is reached and created?

Thanks!
