Ugh I hate it when artists do that xD They sound terrible on stage. I remember when my cousins were listening to Miley Cyrus singing Wrecking Ball live on TV. IT SOUNDED EVEN MORE HORRIBLE THAN THE ORIGINAL SONG!! XD
Of course it did. This is what happens every time when people use things like autotune to boost their "skills". They screw up when they have to play their songs live xD It's actually hilarious to watch :3
