It's a waste of time, and annoys the pig.

Um, are you quite 'sure' about that, several scientific studies show that pigs (and a lot of other domestic ated animals) are happier when there is music in their homes. A lot of animal research stations are always playing music for their mice and rats, making them _much_ friendlier to work with. Although music with a lot of beats in it does tend scare them.
