'Sing Again' returns with Season 4. This program is a rebooted audition that captures the journey of contestants dreaming of becoming new 'famous singers.' The first episode of 'Sing Again - Unknown Singer Battle' Season 4, airing on the 14th, offers a 'one more' chance to singers who desperately want to perform on stage.

Since its debut in 2021 with Season 1, the program has continuously succeeded through Season 3, popularizing the concept of the 'unknown singer battle.' Each season has captured both public attention and high ratings, producing many talented singers. In Season 4, trusted MC Lee Seung-gi leads the panel of judges, including Lim Jae-beom, Yoon Jong-shin, Baek Ji-young, Kim Eana, Kyuhyun, Taeyeon, Lee Haeri, and Code Kunst. Taeyeon joins as a new judge this season and will support the contestants with sincere encouragement.

This season features 81 contestants who have passed the unprecedentedly competitive preliminary rounds and advanced to the main stage. Lee Seung-gi said, "This season is exceptionally diverse. There are so many contestants who will capture the hearts of viewers." Kyuhyun added, "There are gems whose voices are so different from the very first note that you'd think they belong to a completely different species."

'Sing Again' has established itself as a 'legendary audition' by rediscovering numerous singers. In Season 1, Lee Seung-yoon, Jung Hong-il, and Lee Mu-jin made it to the top three, bringing renewed attention to forgotten voices like Lee So-jung, Yumi, and Hajin from Ladies' Code. The stage videos from that time went viral on YouTube, sparking a phenomenon. Lee Seung-yoon's 'Chitty Chitty Bang Bang' surpassed 10 million views, 'Honey' exceeded 20 million, and Lee Mu-jin's 'Is Anyone There?' broke 40 million views.

In Season 2, Kim Ki-tae, Kim So-yeon, and Yoon Sung-yi proved their presence with their skills, and in Season 3, Hong Isaak, So Subin, and Izel demonstrated their talents, confirming that 'Sing Again' is a reliable audition program. Season 4 promises record-breaking performances from skilled contestants. The preview shows a powerful stage that made Taeyeon scream and a moment where Lim Jae-beom admired, saying, "I can't breathe, it's overwhelming." There is also a dramatic performance that moved Baek Ji-young to tears and a moment where Lee Haeri happily said, "I found my eardrum boyfriend."

The contestants' one-line introductions are also intriguing. Phrases like "I am a singer who studied through Sing Again," "I am a singer who has something to reclaim from Hong Isaak," "I am the singer of Lee Byung-hun's favorite song," "I am a singer who was afraid of K-pop," and "I am a singer who needs reconciliation" spark curiosity about the stages they will present.

The judges' messages reveal the season's character. Kyuhyun advised, "You have to love yourself the most for listeners to live through your voice together." Taeyeon said, "I hope you express yourself freely," and Lee Haeri encouraged, "I hope you find how much you love music within yourself and continue making music for a long time."

'Sing Again' has returned to the essence of audition programs each season, proving the value of 'the sincerity of unknown singers.' Rather than flashy editing or sensational competition, it has moved viewers with the stories of those who have quietly sung without fame. This season also reinforces the core message of 'giving one more chance to those who desperately want to perform,' reminding us of the true meaning of auditions.

The production team stated, "In Season 4, many 'Sing Again Kids' who have nurtured their dreams and skills through Sing Again will participate and show amazing stages," adding, "You will discover the raw charm of 'true unknown' singers who have never had a chance to appear in the media and new faces who are talented unknown singers."

Returning after two years, 'Sing Again 4' promises new emotions filled with each contestant's story and voice, as suggested by its subtitle, 'A reboot audition that calls me once more.' Attention is focused on whether another star will be born to continue the legacy of Lee Mu-jin, Lee Seung-yoon, Kim Ki-tae, Hong Isaak, and So Subin. 'Sing Again 4' premieres on the 14th at 10:30 PM.
