Remove given string from all fields

Is there a way (maybe with the scrub plugin?) to remove a specific word or phrase in every field in which it occurs?

For instance, I would pass the word “rock,” and I would then have:

  • an album called “For Those About To” by AC/DC
  • an album called “Original Soundtrack” by “Original Cast of The y Horror Show”
  • a track called “We Will You” by Queen
  • countless tracks with a genre of " ‘n’ Roll"

and so on, across every tag Beets supports.

Is there any way to do this other than writing a batch script to attack each tag separately?
