[TOMT] That one music video

There was this one music video that I always watched in middle school and I can't think of the song name or the artist. Its a bunch of people running (maybe in slow motion?) and i think there is a women almost leading the crowd/who is also the singer. It should have been maybe 6-7 years ago. It seemed sunny and everyone was happy. I feel like the artist was along the lines or Ingrid Michelson/Yael Naim but maybe thats me just getting it mixed up.
