As with most of my lists about favourite films, books or music, my choices are subject to change, depending on my mood. So this list holds true, but only for now:
  1. Ain't Nothing Like The Real Thing (Marvin Gaye and Tammi Terrell, 1968)
  2. Don't You Want Me, Baby? (The Human League, 1981)
  3. Don't Give Up (Peter Gabriel and Kate Bush, 1986)
  4. The Boy Is Mine (Brandy and Monica, 1998)
  5. It's So Easy (Sheryl Crow and Don Henley, 2002)
