Movies with no musical scores

Musical scores are some of the best parts of a movie that I don't notice. It is a combination of matching what is going on with the movie and enhancement with the score. Except for a few iconic scores, I don't notice scores much if it blends really well if that makes sense. It begs the question if movies we revere could stand without any musical score.

I don't recall seeing a movie with no musical score at all. I see that they are out there and date back from the 70s until at least 2014- but I never saw any of them. Can anyone cite any?
