The variety of songs and singers appeals to young and old alike. Another reason for the show's popularity is that all the performances are live, with no lip-synching, allowing viewers to get a taste of the "real thing."
由於歌手須在現場演唱，不能放錄音帶對嘴表演，通常非實力派歌星難以勝任，所以觀眾能在節目中欣賞到「硬裡子」的歌舞，也因此造成口碑。一有口碑，雙星報喜便逐漸「近悅遠來」。
