hm, I think it's something else. I played like one pet I think but I'm pretty sure I heard the song more than once. Haven't played Sims 3 in years so can't remember exactly when it played but it sounds very familiar.
I can't remember, but I thought it was the music that plays once someone has died. Not the grim reaper music, but a song that played once they were dead.
ETA: possibly when it was a Sim's romantic partner when they had a high romantic relationship?
However, apparently there's a glitch that makes it play sometimes even when there isn't a relationship that's just ended.
I was literally about to comment that it's from a divorce!
I know this because I'm a horrible person and divorce or break up my Sims when I get bored of their partner! xD
