In the advertisement, it sounds like new age or something electronic. It goes on to pick up the pace, and a woman with a soothing voice calmy says "Isn't it great how things just come together?"
After that, the singer, who sounds a little like John Newman or Wheezer sings, "I'm tiiiiiiiired" or something like that.
Thanks in advance for the help. It's been stuck on my mind for the past 2 months.
