Toni lipped. Beyoncé has her prerecorded vocals on point too. They all learned from Janet on how to make a prerecorded vocal sound live. I don’t care how many hours Beyoncé danced in heels as a child, her voice will sound tired doing the type of choreography she does. She performed live at Billboard Music Awards in 2011 and you could clearly hear what a live vocal from her actually sounds like while dancing compared to her other performances where’s there’s not a single out of breath moment or vocal mess up. Real vocalists have on and off days. See Mariah.
