I usually go with the title and credits from the cover image (when it includes them).
Different digital platforms have their own policies for formatting titles and credits, and I figure that the cover image is closer to what the artist/label intended. (Even in the case of a Bandcamp release that was uploaded by the artist, I usually stick with what’s on the cover – I assume that more thought went into creating the image, and the text on the webpage often includes additional words to improve searchability.)
Yes, I have always done it this way. If there is a conflict between the artist credit on the digital platform and the artist credit on the cover, I will use the one from the cover. If the cover is not available, I will look for images of the physical disc’s back or tracklist.
