This week on Pop Culture Happy Hour, NPR Monkey See's Linda Holmes and Glen Weldon are joined by Tanya Ballard Brown and Code Switch's Gene Demby to talk about Fox's hip-hop drama Empire. Then they'll chat about the recent discussions about public radio voices, and broaden the conversation to the variety of voices you hear on the radio. All that, plus What's Making Us Happy.
