I always have sex, drive, and fall asleep to Mozart. That works for me. Not necessarily a Swiftie, but I respect her marketing power. But Mozart relaxes me.
I like keeping on some very soft, smooth (instrumental only) jazz on in the background. It's a nice vibe and can help fill awkward silence. Thankfully these days I have an Alexa. I am remembering the "old" days with my CD player.
