i—actually, the soundtrack style guideline says—you should take reference from the cover art. and no, the booklet is not what we generally mean by “cover art” even if its images may be added to the “cover art” section.
Thanks Kid_Devine, that seems to amount to “This is what the SG says”.
I’m trying to see what the benefits of not using the booklet info is.
The only benefit I can see is that previously added Releases, where the booklet was not used, would be only medium quality data if a change to using the booklet was made.
