Pop music surrounds us, but how often do we really listen to what we’re hearing? Switched on Pop is the podcast that pulls back the curtain on pop music. Each episode, join musicologist Nate Sloan and songwriter Charlie Harding as they reveal the secret formulas that make pop songs so infectious. By figuring out how pop hits work their magic, you’ll fall in love with songs you didn’t even know you liked.

Anderson Paak and Bruno Mars have joined forces as the duo Silk Sonic, and their first release “Leave the Door Open” suggests that their collab is as natural as peanut butter and jelly. The song exudes throwback vibes through its lush harmonies and sensuous lyrics. But this isn’t any run-of-the-mill exercise in empty nostalgia.

Silk Sonic have a very specific sound in mind that they’re reviving for 21st century audiences: Philly Soul, the sophisticated 70s sound that “put a bow tie on funk.”

Charlie and Nate aren’t the only ones trying to blow the dust out of the grooves of “Leave the Door Open.” Songwriter Tayla Parx, who’s worked with everyone from Ariana Grande to Panic! At the Disco to Anderson Paak himself, joins the hosts to help explain how Silk Sonic created such a catchy track, and why modern listeners might be ready for a blast from the past.
