The new ABC comedy Mixed-Ish [1] premieres on Sept. 24, and it should come as no surprise that national treasure Mariah Carey [2] sings the catchy, funk-inflected theme song. "In the Mix" debuted at POPSUGAR and ABC's "Embrace Your Ish" event in LA earlier this month with a splashy video that features the cast cutting a rug [3], along with cameos from Carey's 8-year-old twins, Moroccan and Monroe [4], who also helped out on vocals. Listen to the tune now, and be sure to watch Mixed-Ish on ABC. [5]
