Tools, just like a carpenter needs a hammer, singers sometimes need vocal tuners, and even teleprompters. Just like mixing engineers cut and paste vocals to get the perfect one; whatever it takes to put on a killer show. I don't even have a problem with someone lip syncing if they are under the weather, as you go to the show to see the entertainer in the flesh and the show; otherwise you could just sit at home and listen to the album, no one needs a teleprompter for that LOL.

Psalm 57:7 My heart, O God, is steadfast, my heart is steadfast; I will sing and make music.
