Tayla Parx uses life's everyday dramas as fodder for her always-relatable pop songs: consider Alicia Keys' tropical-flavoured "In Common", about a woman worried her new partner might be as "messed up" as she is, or Ariana Grande's "My Everything", a brittle piano ballad that mourns a great lost love. She also helped craft Mariah Carey's swaggeringly confident breakup anthem "Infinity", which is powered by euphoric strings and brass.
