Fight Song by Rachel ifogetherlastname, that came out a few years ago. It was EVERWHERE! I couldn't escape it. How pretty much every person in my family loathes the thing.
Uptown Funk was ruined for me after these kids at a dinner party kept singing it on repeat and screaming into the wrong microphone. =_=
There's this song that I can't stand, but I don't know what it's called and I don't want to promote it by trying to look it up. It's pretty much a guy talking about all of these nice material things that he's going to give a girl, but specifically he'll give her those things because he himself likes them? It's like "Have this gift that I'm giving you specifically because it's not an inconvenience to me and I would have bought it anyway."
