Elvis, me being about to start a tag to Lucifer was not an invitation to start up with (You're the) Devil in Disguise.

ᴠɪʙᴇs ᴅᴇsᴜ I'm now tempted to let it start playing on the jukebox at the bar to give Gabriel a reason to death glare at it. (Or alternatively, give him interesting mental images.)

...yes

If it does a string of thematically appropriate songs, he might suspect Lucifer of rigging it to play them.

Bwah. Nah. He'd just start singing them himself

Gabriel likes playing with jukeboxes to make them play what he wants them to, hence him suspecting Lucifer's hand in things.

Oh, Lucifer likes his thematically appropriate soundtrack. He just usually has a DJ to play it for him

Well, he's in the wrong place for that.

Very wrong. He'll be slightly sulky about it

Gabriel's sure that he'll get over it.
