It’s not as much as the typical theme park land where there’s always a music track being pumped through the speakers, but it’s more than Pandora has.
I wanna say I heard music outside Savi’s the last time I was there, but it honestly could have just been the Docking Bay patio track carrying on the wind. There’s also a couple radios scattered around the land, but I don’t know if they’re always playing music or if it’s sometimes random chatter.
