You could probably make various arguments on how to tag music based on multiple factors including personal preference.
I'm going to use Moana as an example because it's very similar, and it's a Disney album I have tracks properly tagged for.
This is how I currently have Where You Are tagged:
Display Artist: Christopher Jackson, Rachel House, Nicole Scherzinger, Auliʻi Cravalho & Louise Bush
Artist: (all of the above separated out into individual Artist tag entries)
Display Composer: Lin-Manuel Miranda, Opetaia Foa'i & Mark Mancina
Composer: (all of the above separated out into individual Composer tag entries)
