If I was playing music for the pigs it had to be a specific few genres, which always made finding radio stations for them a tad difficult. They liked rock, a bit of soft metal, and hated pop music lol.
They won't need it, specifically. As for whether it would be helpful, I can't answer. I think if you do it, leave it on for a bit while you're at home, see how they're taking it. And keep the volume relatively quiet, aye.
