This song doesn't need to be this catchy.
And yet, it is.
Also, this is the first Charli XCX song on any of my playlists. Again, the song is super catchy, but for some reason, the vocals and the music are almost at the same level, so when I first heard this on SNL, it felt like Andy Samberg's vocals were drowned out by both the arrangement and the laugh track.
But yeah, once I heard The Lonely Island version, I can safely say that this song is right.
