There's no right way to put together a wedding playlist. But there's definitely a wrong way. And, typically, they're done the wrong way.
As a general rule, if "shuffle" is in the song title, don't play it. The “Cha Cha Slide” is another wedding staple that nobody enjoys. Besides being the dumbest dance ever, it drags on for seven agonizing minutes. By the time Mr. C the Slide Man demands “two hops, this time” the dance floor’s been cleared. And sweating through your rental tux to “Shout” has become as painful a wedding formality as hand-written thank you notes.
