What’s the one song you can’t listen to anymore because of an ex?

For me, it is "Our Song" by Taylor Swift. We started dating in tenth grade and that was our anthem for seven years. I had to end things last month when I realized he didn't actually love me, he just loved the idea of a girl who would stay small and "listen" to him. He started hating my ambition and kept telling me I should be more like his mother, stay home, and keep my head down. I’m twenty-two and just starting my career, and I couldn't shrink myself for him anymore. Now that song just reminds me of someone who wanted to dim my light.
What song is ruined for you?
