Lady Gaga and Bruno Mars, ‘Die With a Smile’

Lady Gaga and Bruno Mars — two superstars who have been relatively quiet on the music front in recent years — team up for the first time on “Die With a Smile,” a romantic, lightly apocalyptic slow-dance that offers both the opportunity to belt to the rafters. Despite the music video’s George & Tammy cosplay, there’s not much of that ever-so-trendy twang to be heard on the actual track. Instead, “Die With a Smile” is a lush, soft-rock torch song accentuated by weightless, trebly guitar. “If the world was ending, I’d wanna be next to you,” they sing together on an anthemic chorus, striking the right balance between grit and polish — just two consummate professionals doing their thing.

Post Malone featuring Chris Stapleton, ‘California Sober’

Post Malone and Chris Stapleton sound like they’re having a blast on the rollicking “California Sober,” one of many country duets featured on Posty’s new album “F-1 Trillion.” The twangy foot-stomper spins a classic country yarn: picking up a good-looking hitchhiker who drinks all your whiskey, picks your pockets and leaves you with a lingering kiss goodbye. “Damn bottle was dry,” Post Malone croons in a voice that blends well with Stapleton’s gravely drawl. “Kinda wanted to cry.” ZOLADZ
