Mr Brightside by the Killers. The tune was good and felt energetic when it came about, but it's about a guy being cheated on. Having had someone cheat on me around the time it came out it hit really close to home and I just don't enjoy listening to the song.
The problem with being in the UK is that it's so overplayed and I just have to tune it out.
During lockdown in April 2020, the frontman looked back at the video and noted: "It's just a song about betrayal. I was betrayed and I was able to turn it into a masterpiece".
From the article "The lyric is about a man who is obsessed with a girl that is seeing another man… and the thoughts that go through his head, imagining what they’re doing behind closed doors…" I guess I was wrong, it's envy not jealousy.
I second one of the other commenters who says that the song is about the perception of being cheated on. It's funny, after the first day I ever went on with my partner that song played and for a little while we considered it our song, then eventually kind of faded as they both realized the song didn't relate to us very well. Now I can look back years later, after going through a lot of therapy and self enrichment and I can realize that those kind of paranoia really did plague our early relationship. I'm glad that we were able to move on from it
