You’re looking in two different places, and we do consider each separately. The tracklist – as seen on the cover (first two images) and supported by the CD – is what determines what artist credit we have. In this case, all of the tracks are given with only their name, and so we fall back on using the release artist from those same images. What you seem to be concerned about is the “Credits” list of everyone who was involved, and for us that has no bearing on who we put in the “Artist” field because most people, when looking at a disc in their hand, aren’t going to pull out the booklet and read through the small text to find every single person who played a role before telling their friend “Yeah, this is…” What that list does affect are the relationships we add on top of the recording afterward. I’m not seeing any inconsistency in this release either, but if there is something we’re missing that we haven’t covered in our explanations, do let us know.
