This is a presumably incomplete list of movies whose soundtracks include different versions of the same song, one sung by characters in the movie, and a cover by a pop artist or artists, which usually (but not always) plays over the end credits. I will not be including songs that were recorded years later for "special edition" soundtracks. So far, all the movies on the list are animated, and almost all are from Disney. I'm not sure how many non-animated or non-Disney examples exist, but I assume some might exist. (Movies will be listed chronologically.)
