出道23周年的2021年12月9日。 时隔许久以深情抒情歌曲回归的名牌主唱申智（ 신지）的单曲专辑《 맴찢(Heartbroken)》 以新造词“맴찢(Heartbroken)"为曲名创作的这首歌曲，抒情的让人想起过去，感性的旋律是一流的。 毫无悬念堪称国内最佳主唱申智（ 신지）的嗓音，完成了适合冬季的悲伤叙事曲。 这张单曲专辑《 맴찢(Heartbroken)》是申智正在活动的组合"高耀太"及以多种风格活跃活动的KZ、郑秀敏、D-DAY、Noise_bo2参与了作词和作曲，提高了完成度， 可以说这是一首包含申智杓抒情曲的经典歌曲。 在歌曲的开始的主歌部分，比起哀切，更平静地讲述自己的情况，以抒情旋律和音色开始从副歌部分开始变成有号召力的悲伤旋律是欣赏重点。 Credits Artist 신 지 Produced by WITH String by KZ,정수민 Piano by KZ,정수민 Guitar by 이태욱 E.Piano by KZ Bass by KZ,정수민 Synthesizer by KZ,정수민 Drum by KZ,정수민 Chorus by 송화영 Recorded by 최자연@wsound Vocal Edit Engineer by DINT@DINT Studio Mixed by 조준성@wsound Mastered by 최효영@SUONO Executive Produced by AOB Entertainment / KYT Entertainment
