Some “singers” have said that there’s nothing wrong with lip syncing.
If what they say is true, then how come these “singers” never tell people in advance that they are lip syncing?
In my opinion, any “live” performer who is lip syncing should tell their audience that they are lip syncing, before they starting doing it.
And if they are charging money for their “performance,” they should tell you before you pay money for the ticket.
Otherwise, they are guilty of lying and fraud.
