“Bad” Singers With Autotune vs REAL Singing Voice (Same Song Comparison)

I compared the real voices of some "bad" famous singers with and without autotune side by side. I compared the before and after songs with acapella, live performances, mic feeds and isolated vocals. List of singers who "can't sing": 1. Britney Spears 2. Selena Gomez 3. Katy Perry 4. Kim Kardashian 5. Lana Del Rey 6. Charlie Puth 7. Jennifer Lopez 8. Madonna 9. Britney Spears (again) 10. Mariah Carey 11. Ariana Grande (good performance)
