They've been in the trenches, I just know it. Not every singer is able to emote heart break as well as these 10. I've kept the list to those who are still alive. Care to add an honorable mention?
  1. Adele
  2. Beyoncé
  3. Mary J. Blige
  4. Sam Smith
  5. John Mayer @john
  6. Duffy
  7. Ed Sheeran
  8. Tracey Chapman
  9. Kelly Clarkson
  10. Leona Lewis
  11. I nearly put the specific song that got them on my list, but so many have more than one…hence their being on the list.
