Today I was tagging my music related to Ghibli films and I found a release like this that has the Artist Credit for the tracks listed to 久石譲 and then has the actual performers of the songs listed as recording relationships.
AFAIK, in these situations shouldn’t the person who performs the vocals be listed on the AC field? The booklet lists 久石譲 as composer and then lists the lyricists and vocalist for every song.
To be clearer, this release is for songs from the movie rather than the movie soundtrack itself.
