The Best of Jerry Butler: The Millennium Collection collects 11 of the soul singer's definitive hits, including "Only the Strong Survive," "Hey, Western Union Man," "One Night Affair," "I Dig You Baby," and his duet with Brenda Lee Eager, "Ain't Understanding Mellow." A new essay about Butler and new remastering add to this collection's worth; though it may not be the most comprehensive Butler retrospective available, it's still a good introduction to his career highlights.
