"Passing By" (Korean: 스쳐간다; RR: Seuchyeoganda) is a song by South Korean singer-songwriter Roy Kim. It was released as a digital single on November 27, 2012, and distributed through CJ E&M Music. "Passing By" was the winning song of Mnet's talent competition series Superstar K4.
Four days after winning Superstar K4, Kim's digital single "Passing By" was released.[1] In its first week of release, the song charted in the top 10 of several music portals and charts in South Korea.[2] It peaked at number six on the Gaon Digital Chart,[3] and number nine on the now-defunct BillboardKorea K-Pop Hot 100.[4] As of February 2013, "Passing By" has sold nearly 654,000 digital copies in Kim's native country.[5]
As "Passing By" was only released for Superstar K4, it was not heavily promoted. Aside from a performance on Superstar K4,[6] Kim also performed the song at the 14th Mnet Asian Music Awards on November 30, 2012, followed by Mnet's M Countdown on December 13 that same year.[7][8]
