Yeah, for things that are dictated by platform limitations, I would go with whatever source aligns more with artist intent.
I guess in this case it is hard to tell if the usage of “&” vs “feat” is on purpose: example album on 7digital. But there is a chance it is more accurate than what the label/designer did on the CD.
edit: Looking at it again, even the track titles have the “feat” artists specifically included. It seems unlikely that this was by accident - I’ve put in a vote and note
