How many pop stars lip sync?

The number of pop stars who lip sync varies widely, as it often depends on the specific performance context and the artist's preferences. Many artists may use lip syncing during live performances, particularly in large productions or for televised events, to ensure vocal quality and stage presence. While some pop stars embrace live singing, others may rely on pre-recorded tracks for various reasons, including choreography demands and vocal health. Ultimately, it's a common practice in the industry, but the extent varies by individual artist.
