One of the most successful pop duos in history, the Righteous Brothers owned the mid-1960s love song space with an epic, soul-drenched style. The brilliant "Unchained Melody" was born anew in the film Ghost. It joins You've Lost That Lovin' Feeling"and "Soul and Inspiration" on heavy radio rotation but all of these songs deserve a place in your heart. "Just Once In My Life" and "On This Side of Goodbye" are dramatic stunners, while "Little Latin Lupe Lu" proves the duo could rock with bite. Fun fact: They were dubbed "blue-eyed soul" by a DJ who was surprised to learn they were white.
