As you know, JP Saxe's "If the World Was Ending" f/Julia Michaels (Arista) is a monster. Now an array of stars from varying genres have joined forces to sing a new socially distanced version of the song, proceeds from which will aid Doctors Without Borders. You'll find a complete list of participants joining Saxe and Michaels below, which includes Sam Smith, Niall Horan, Keith Urban, H.E.R., Alessia Cara, Florida Georgia Line, Kelsea Ballerini, Kesha, FINNEAS, Jason Derulo, Noah Cyrus, Pink Sweat$, Fletcher and Zara Larsson, among several others. The direct donation link for Doctors Without Borders is here; if you make a large enough contribution you'll receive a video of John Boulos doing an elaborate interpretive dance to the song.
