The fifth track from SM’s “STATION: NCT LAB,” “Birthday,” by Ten, is an R&B dance song that lets you completely feel Ten’s delicate vocals. It has minimal drum repetition, marimba sounds, and dynamic drops in the bridge section that creates a dreamy atmosphere, as well as romantic English lyrics that compare a day with a lover on a happy birthday. On April 23, 2022, the song was previously revealed at the “Great Dance Crew” competition in China.

Through solo tracks like “Paint Me Naked,” “New Heroes”, and “夢中夢 (몽중몽; Dream In A Dream)”, Ten has also been praised for his complex musical style and exceptional performance abilities.
