Music: I Want to Know What Love Is | Foreigner or Mariah Carey?

Butterflies! So my post a few days ago about love has had me thinking about one of my favorite Mariah Carey songs "I Want to Know What Love Is" all week, I literally can't get this song off my mind. Love never gets old, I mean who doesn't want to be loved on? Even the toughest of the hardest people secretly desire to be loved and that's why I feel this is a timeless track. It was originally performed by the 70's rock group Foreigner; from their 1979 Head Games album. I like both versions of the song...it's a great song. What do you think...who did it better?
