Pet Shop Boys "West End Girls"

During the 1990s (and even today), many Adult Contemporary radio stations featured "forgotten" '80s music during specialty lunchtime, weekend or nightly features (like "80s @ 8"). These features highlighted '80s songs from the station's playlist and sprinkled in some "deeper cuts" that weren't part of the radio station's core playlist--such as "West End Girls" from Pet Shop Boys.

Pet Shop Boys "What Have I Done to Deserve This?"

Credit the Pet Shop Boys for revitalizing Dusty Springfield's career in 1987.  The synth-pop duo added Dusty's vocals to "What Have I Done to Deserve This?" resulting in a worldwide smash hit -- and the first time Springfield's name was back on the charts since the 1970s.  This also rekindled interest in Springfield's older music and introduced legions of new fans to her.  In 1990, the Pet Shop Boys continued to promote Dusty by writing two additional songs for Springfield's Reputation album.
