Soundtrack is better or more popular than the movie.
List entries do not necessarily mean the movie sucks. In a few cases I love the movie more (hence the "more popular" option). In some cases it's a matter of comparison/preference
*This is for films with song soundtracks, not scores, in which case the list would be a lot longer and maybe less random/weird. For the record, my first entry in such a list including score would be Sherlock Holmes. I am aware that in a few cases here there is a fine line between score/soundtrack
