While there are many great songs that BTS was actively involved in writing the lyrics for, this book presents a selection of 10 songs in total, including Yet To Come from Proof (2022), to ensure adequate coverage of the deeper implications of the lyrics and various anecdotes related to the songs. The selection was based on two surveys about fans' favorite BTS songs conducted in 2020 and 2021, with responses from approximately 145,000 and 204,000 ARMY, respectively.We also analyzed the set lists from several performances and fan-meets, from LOVE YOURSELF TOUR in 2018-2019 to BTS PERMISSION TO DANCE ON STAGE in 2021-2022, and classified 10 songs into categories such as opening song (OPENING), dance number (DANCE), song dedicated to ARMY (FOR ARMY), and closing song (CLOSING), which are based on the progression of a concert. We hope that reading this book will give readers an experience similar to being at a BTS concert.Each chapter focuses on one song and consists of three sections: About the Song Sing Along as You Fan-Chant Lyrics Inside.Two or three chapters make up a part, and each part ends with someconcert-related episodes or a feature covering an aspect of Korean culture that may help deepen readers' understanding of the songs.In the About the Song section of each chapter, there is a brief introduction of the album and the song, as well as little anecdotes from BTS' lyrics writing and official interviews.
