Naughty Boy and Sam Smith's 2013 hit "La La La" blends an infectious pop beat with poignant lyrics about emotional self-preservation and ignoring unwanted truths. The song's repeated, titular refrain acts as a metaphorical, childish defense mechanism to block out communication breakdowns and the overwhelming noise of a difficult relationship. The lyrics explore this conscious decision to detach, as well as the sense of empowerment found in choosing silence over painful, repetitive arguments. You can find the full lyrics at: Genius AZLyrics
