On May 11 at midnight KST, BTS released the tracklist for CD3 of their upcoming anthology album 'Proof,' which primarily consists of members' demo versions of past songs. 

To everyone's delight, the 9th track is V's Demo version for "Spring Day," the group's title track from their 2017 album "You Never Walk Alone." 

"Spring Day" is one of BTS's legendary songs, and it currently holds the record of having the highest unique listeners on MelOn, South Korea's largest streaming platform. 

Kim Taehyung previously shared snippets of his demo version years ago, and fans are excited to finally hear the song in its full version. 

In addition, Taehyung's soulful masterpiece "Singularity" from the 2018 album "Love Yourself: Tear" is added to CD2 of the anthology album, and fans are hoping to see its iconic, seductive performance in BTS's concerts in the near future.
