BTS’s Live Singing on Surprising “Spring Day” Performance Sparks Intense Criticism
BTS is facing controversy after Jin brought V and Jimin on stage during his second encore concert in Seoul on October 31, 2025.
The trio performed an unrehearsed version of their fan-favorite “Spring Day.” The performance surprised fans in the venue, but social media reaction quickly turned harsh.
Netizens slammed the lack of preparation and no backing track, saying their raw vocals didn’t meet expectations for such an iconic BTS song. Many called the vocal tones “the worst in K-pop” and claimed it made their “ears bleed.”
The surprise came after Jungkook’s guest solo the night before, where he performed “Standing Next To You.”

Following Jin’s act, V and Jimin joined in for the live “Spring Day” that wasn’t rehearsed or backed by track.
Fans online pointed out the vocal performance missed the mark. They said it fell short of standards for a song that’s a career-defining BTS moment.
Others went so far as to say:
best vocalist in k-pop they said? my ears bleeding

Some fans tried to defend the group, saying the moment was spontaneous and meant as a gift to fans, not a polished stage.
Still, backlash swelled as several viral tweets mocked BTS’s live vocals and questioned their current singing skills after 12 years in the industry.
“they didn’t rehearse that song” baby they’re performing the biggest song of their career in sk and these men will celebrate their 12th anniversary soon, singing is vocalists’ job but seems like they can’t do sht without loud backtrack
