1. Sing Again 30号歌手 – Chitty Chitty Bang Bang 我茫然地希望某人在选秀节目中唱这种编曲（我也不知道是什么）的歌曲。 很感谢现在我拥有这个机会，能让我挑战一下。这个挑战是需要勇气，我冒昧借用李孝利前辈的自信。30号歌手的传统抒情曲 滴滴叭叭！啊，其实不用特意躲开也可以。 (by 30号歌手) 2. Sing Again 37号歌手 – 春夏秋冬 金贤植的国民金曲《春夏秋冬》以强烈的摇滚风格为基础，在这个舞台上由偶像出身的37号歌手重新诠释，强力不演唱力给人留下深刻印象。还有，在后半部分抽取了唱「江山」的另一首热门歌曲 李仙姬《美丽的江山》的高潮部分，营造出动感。 3. Sing Again 63号歌手 – 口哨 我记得小时候因为一起生活的猫，令哮喘恶化，最后只好送牠去被领养。 一直没有回首那离别的日子，这次代入把那只不是离开我，而是被我送走的猫的感情唱了出来。 (Credits) Executive JTBC / JTBC studios Production ShowPlay Publisher Agent Major7 E&M 음악감독 - 권태은 Mixing - 강해구 at Lunchsong Studio 1. 싱어게인 30호 가수 – Chitty Chitty Bang Bang Lyrics by 이효리, Antwann Frost, RONALD FROST, ANETRA TERREL, CC Productions, RYAN JUHN Composed by 김지웅, Antwann Frost, RONALD FROST, ANETRA TERREL, CC Productions, Ryan S.
