Listen to The Cars’ 1981 hit, “Shake It Up,” in comparison to their late-70s material, and one can hear how the band did just that. With a sound that at first was more rock-oriented with tracks like “Just What I Needed,” “Good Times Roll,” You’re All I’ve Got Tonight” and “Moving In Stereo” (yes, the song that played over that Phoebe Cates scene from Fast Times at Ridgemont High), “Shake It Up” is pure pop-new-wave. With the birth of the MTV/music-video generation beginning in 1981, Ric Ocasek and the band embraced this sound through the new decade, with pop-ballad, “Since You’re Gone,” and later with 1984’s Heartbeat City (“You Might Think”; “Hello Again”; “Magic”; “Drive”).
