Jazz era

I find it funny how the music of jazz was viewed as "devils" music, and how parents did not approve. As we watched the movie Jazz kids in class, the dancing and music seemed completely appropriate and old school. It actually had an innocent vibe. The dance seemed tasteful and adorable. Ironic how today its viewed this way, when during its prime it was frowned upon. This makes me wonder if at some point in the future, rap music will be view as innocent. Will the vulgar lyrics seem "not to bad" at some point? Decades from now how will our grandchildren view our media?
