Inspired by karaoke, the show aims to let everyone have a good time regardless of their singing skills, and for everyone to come together and have fun no matter their age. The 4 celebrities are a team called, 'T4'. The cast will compete with their friends to see who can pull off the most fun and energetic musical performance. Unlike other singing competitions that are focused on singing skills, this show will focus on creative stage performances and fun energy from the performers. Each episode usually consists of 3 normal rounds (to determine the karaoke room size for the final round), and 1 final round to determine the winner of the episode. The winner of each round (including the final round) is decided on an audience of 100.
