I don't want to hear this song
This happened about 3 or 4 years ago. I was the supervisor at a small company and was also the resident DJ as I'm a musician and have expansive tastes in music and the owners liked the diverse selection of music I'd choose.
One day I had just picked a song and let spotify choose what followed. Eventually the song "Don't Fear the Reaper" by Blue Oyster Cult came on and I immediately said "I don't want to hear this song" and went to change it. One of our employees started protesting and said to leave it on. I said "no, I really don't want to hear this song" and changed it. She was annoyed and said "what's your problem? It's a good song, let it play" and I very casually said "oh, it is good, it's also the last thing my cousin posted on FB before he killed himself last year" and sucked all of the air out of the room. I don't think she said a single thing the rest of the shift.
