Ooo, wow. Tough choice. Although, I think "Ben" vs. "Music & Me" would be a more interesting match, since "Who's Loving You" kinda sticks out with its overall "feeling" more in the blues realm than the other two. With that matchup in mind... Both are incredible songs and vocals, but "Music & Me", with its guitar instrumental makes it a more timeless song; this makes it edge out against Ben to me, if ever so slightly. Again, all 3 songs are incredible though. Of the three, "Who's Loving You" is my personal favorite.
