Not a Call for Sanitized Art

After listening to a certain popular song multiple times (sometimes from the burned CD and more than I would like from the auto-repeat in my mind), it made me think of hygienic art. This particular song struck me as painful and self-absorbed. I understand the idea of art-as-therapy; I understand the concept of catharsis. I also wonder if some art isn't like personal hygiene--essential to perform but best kept private.
