I believe that if you can possibly bear something-a song, a film, an experience-you should. Everything has a purpose and therefore even the least sophisticated creation may have some glorious truth to be gleaned.
Oscar Wilde said all bad poetry is sincere, which perhaps explains why even some of the most monotonous rock songs are still good. Think of "American Music" by The Violent Femmes. From an aestheticist's eye, that song sucks, but I do love it so, because I do like American Music!
That being said, if you glean no truth, and cannot find someone to satisfactorily find it either; or worse, find a lie, the "something"-song, film, experience-should be cast out with great force, as with the devil.
