I used to fucking HATE this song. Until I realized it was a joke. And the beat got to me.
My least favorite song is either Selena Gomez - Good for you. or Ariana Grande - Side to Side.
They are both annoying top 40 generic, but catchy tracks that play on every radio station but are boring as all hell. And since I take a bus, I hear these songs, Starboy, and Closer at least once a day. And although I don't really like Starboy, it's interesting to say the least.
