1. Kenny Rogers & Dolly Parton - "Islands in the Stream"
The Bee Gees — Barry, Robin, and Maurice Gibb — worked with Kenny Rogers on his 1983 country chart-topper Eyes That See In the Dark. The fact that they wrote this fidelity-minded smash surprised people —although their handiwork is made plain by the exquisite harmonies on its chorus. (That chorus returned to the pop charts 15 years later, when Mya and Pras appropriated it for the briefly ubiquitous "Ghetto Superstar.") The blindingly obvious chemistry between Rogers and Parton turbocharged this track's popularity, and it became the Number One song of 1983 and the second crossover hit for both of the Nashville superstars.
