Music's greatest duets: when two is better than one

Great duets have surfaced throughout the history of popular music, evoking a magic that one voice simply can't convey by itself. Duets between Bruno Mars and Rose ("APT.") as well as Kendrick Lamar and SZA ("Luther") have commanded the top of the charts in the past year, and you'll turn up other smash duets no matter how far you go back in time - Lil Nas X and Billy Ray Cyrus (2019), Lady Gaga and Beyonce (2009), Nelly Furtado and Timbaland (2009), Brandy and Monica (1998), Michael and Janet Jackson (1995) ... Keep going and you'll find everything from Tom Petty and Stevie Nicks to Dolly Parton and Kenny Rogers to Elton John and Kiki Dee - even Frank and Tina Sinatra. This week the hosts of "How We Heard It" explore their favorite duets - by both the dream teams and the unlikely duos - and why they hit so well. And since these music vets can't resist throwing a dig now and then, they also look at the duets that underperformed and even some that flat out bombed. Not ever pairing is a match, you know.
