Step into your platform shoes, pull on your bell bottoms and rock a sparkly top — you're headed back to the '70s to experience pop music in its prime. The sweet-as-"Honey Honey" melodies. The foot-tapping beats. The belt-worthy lyrics that make you laugh and cry. Guilty pleasure? Maybe. But ask any karaoke regular, wedding guest — or anyone you know — when ABBA's playing, you can't help but crank up the volume, sing along and start moving. Because in the sunny glow of this pop phenomenon's tunes, even if you have two left feet, you know, deep inside, that You Can Dance.
