'제시(Jessi)' 《怎样的 X》 因《NUNUNANA》而成为热门话题的Jessi时隔8个月以《怎样的 X（What Type of X）》回归。 Jessi问听众们："我像是怎样的X"。 "和你不同并没有错"，"不要判断，人生是不确定的"，这是一首毫无保留地坦率表现了Jessi独有的不同层次的自信和自尊心的歌曲。 Pop Rock风格的强烈Cindisizer和Trap节奏的Track加上独特的吉它伴奏和中毒性的副歌充满魅力，特别是与最后副歌部分要爆炸的吉他声相融合的Jessi的歌声让人感到喜悦。 [CREDIT] Lyrics by PSY, Jessi, johnjohn, JAE RO, KOALA  Composed by PSY, Jessi, 유건형, CuzD, johnjohn, JAE RO, 도나(DONNA), SPACE ONE Arranged by 유건형, CuzD, SPACE ONE Synth by 유건형, CuzD, SPACE ONE Guitar by 고태영, CuzD Chorus by Jessi Recorded by 이기호 @ P NATION Digital Editing by PSY 이기호 @ P NATION Mixed by 구종필 (assist. 정유라) @ KLANG STUDIO Mastered by Chris Gehringer @ Sterling Sound
