BTS’s Live Vocals During Shocking “Spring Day” Stage Trigger Scathing Reactions
BTS’s Jin left fans stunned after unexpectedly bringing V and Jimin on stage during the second night of his encore concert in Seoul earlier today.

The surprise appearance followed Jungkook’s guest performance the previous night, where he performed his solo hit “Standing Next To You.”

This time, the three members chose to perform an unrehearsed rendition of their beloved track “Spring Day,” a song long regarded as one of BTS’s most emotional and iconic releases.
While the audience initially erupted in excitement, the reaction online took a very different turn once clips began circulating on social media.

Netizens pointed out that the lack of preparation and backing track exposed the trio’s raw vocals more than expected. Many claimed the performance fell short of standards required to do the song justice.

Others went as far as to say the three members have the “worst vocal tones” and that the singing made their ears “bleed.”

Some fans attempted to defend the singers, emphasizing that the performance was clearly spontaneous and meant as a heartfelt moment for concertgoers rather than a formal stage. However, this didn’t stop criticism from spreading rapidly, with multiple viral tweets mocking the live vocals and questioning the group’s current singing ability.
“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
