The Mos Eisley Cantina Band in Star Wars. The musical numbers at Jabba's Palace in Return of the Jedi. The celebrations at the end of ROTJ and TPM; IMO it's unclear whether everybody can hear the music in-universe at the medal ceremony in ANH, though. No doubt others from the Star Wars saga.
But how was the music in these scenes "part of the story"?
Well, in the case of ANH, the band stopped playing when Ben sliced off the arm of the alien taunting Luke, then started up again. On the other hand, it didn't miss a beat when Han shot Greedo. No one cared that someone got shot with a blaster; that seemed normal. But pull out a lightsaber, and everyone stopped whatever they were doing. That's telling part of the story right there, since their cover was blown.
Is this sort of thing what the OP is looking for? I don't know.
Little Shop of Horrors,
in case that wasn't mentioned. But, that was originally not
a musical, so was the music really part of the story? I don't know. To me, it was.
