Why don't you talk about this with him.
"Hey Uncle Soondead, you know what's just the worst? People who don't shut up when you get all passive-aggressive with them and just go on and on and ON like they think you actually give a **** about anything they have to say! Don't you just HATE that? Like if some guy, let's say he has terminal... AIDS. And he just comes over and starts going on and on about politics or World War II or whatever and I was just like MAAAAN I wanna go listen to MUUUUUUUSIC, wouldn't you just hate that guy? I sure would."
You certainly shouldn't do anything like put some music on and share it with him, god only knows what would happen then!
