Does Genre Help or Hurt Creativity?

One quick question about music: do constraints of genre enhance creativity, or stifle it? I think the correct answer may be "neither," and that the creativity of a work of music depends almost entirely on the creator. There are swaths of genre-bending music that fail to inspire the listener, and likewise swaths of music created almost exclusively according to the conventions of a given genre, equally uninspiring. A good musician can inspire within or without genre.
