Book of carefully-edited songs, with CD: what Works?

IMHO, this has nothing to do with the issue here. Tchaikovsky revised his symphony, so we have a new version, which is different from a new edition. I agree with the opinion that works are abstract entities, Beethoven’s 9th is Beethoven’s 9th no matter wether the performers used a 19th century edition or the latest Bärenreiter one.

A critical edition of a work is just that, I really don’t think we should have dozens of different works for each work.

I don’t think so. A new work would be appropriate in this case, though.

About https://musicbrainz.org/work/f27cdd94-7f3e-4833-a575-768b47e52f3b: Perhaps I don’t realize how many changes John Glenn Paton did, but if he just edited the score using the arranger relationship is wrong IMO.

Having lots of details about scores, editions etc. is great, but I don’t think MB is the good places for that. In an ideal world, we could link a recording to an edition in BookBrainz to say that the performers used a particular edition.

I fully agree, this would be awesome.

My understanding is that this relationship is meant for Non-PD works which have only one publisher (it’s very common for CDs to list the publisher of Non-PD music).
