This year, Lil Nas X's "Old Town Road" spent a record 19 weeks at number one on the Billboard Hot 100 Chart. Now, it holds the title of the longest running number one single in the chart's history. It's symbolic of the year in music, in a way — an array of new voices and up-and-comers throwing music industry standards out the window. Whether it's Lizzo's love of the flute, or Lil Nas X's combo of country and trap music, the new age of music seems to be twisting, bending and re-imagining the boundaries of popular music.
