Stray Kids’ Kim Seungmin had listeners’ hearts aflutter with his touching cover of Billie Eilish’s romantic ballad “Birds of a Feather”. The 24-year-old K-pop star is the main vocalist of his group for a reason, and his golden voice got a major workout on this 2025 cover, as it had plenty of room to shine over the lone piano part. Seungmin opened the song with a divine verse, and it was instantly clear that he was not only going to knock this cover outta the park, but he was also going to do it in his own style.
The part that got everyone talking was Seungmin’s big vocal runs in the bridge from the three-minute mark onward. Seungmin dropped a heavenly falsetto early in the bridge, and then the emotional high note at the end of the bridge was some major goosebumps territory. While they’ve been a big name in East Asia for some time, Stray Kids only recently started gaining major traction internationally. With performances like this, The Music Man can def see why they’re becoming a global sensation.
Stray Kids uploaded the “Birds of a Feather” cover on March 30, 2025, and in the four weeks since then, it has blown up to 2.5 million views. Fans gave plenty of love for the cover and added comments such as “He sang it as if it was his own song. That right there is the power of Kim Seungmin’s voice” and “I’ve been coming here every day since the day this wonderful cover came out.”
Seungmin has dropped several hit solo covers during his time in Stray Kids. His most popular cover to date is his take on Justin Bieber’s “Ghost,” which hit 6.3 million views on YouTube. This performance is a great showcase for Seungmin’s range, as he shows off a creamy high range in the chorus, while also nailing the breathy low register in the bridge. The Music Man is also a big fan of those flawless harmonies in the chorus.
Seungmin has been a major star in East Asia since he debuted with Stray Kids in 2017. While Stray Kids no longer have official group positions, fans generally consider him to be the main vocalist. With the vocal chops he showed off on the above covers, it’s no secret as to why. In addition to his multi-Platinum success with Stray Kids, Seungmin kicked off his solo career in 2021 with the song “Here Always” for the soundtrack of the K-drama Hometown Cha-Cha-Cha. He has since made numerous solo contributions to soundtrack releases.
