Following the success of JYJ Junsu’s latest single, “You Are So Beautiful,” from SBS drama “Scent of a Woman,” the entire K-pop industry is now turning heads to see if drama OSTs will become a new winning strategy for the trio.

According to JYJ’s agency, C-JeS Entertainment, Junsu’s “You Are So Beautiful” has swept all Korean music charts immediately upon release on August 5th. It didn’t just dominate music portals such as Naver and Daum Music, but it’s also topped various online music charts including Dosirak, Melon, Bugs, and Cyworld.

But this is not the first drama OST track by JYJ to make strides in K-Pop. Last June, when Yoochun sang “A Space Left for You,” the theme song for his drama “Miss Ripley,” it dominated most Korean online sites. Also, JYJ was featured in the OST album for Yoochun’s other drama, “Sung Kyun Kwan Scandal,” which recorded impressive sales numbers for a drama OST.

And now Jaejoong is reported to have participated in the production of the OST of SBS drama “Protect the Boss.” Jaejoong is expected to boost the popularity of the drama with his song writing and singing skills.

“JYJ’s emotional vocal skills help viewers to completely immerse themselves in the drama. When JYJ members actually star in the drama, it adds more power to their vocals and the overall quality of the show,” an official from the drama’s production crew said.

“I think part of the reason JYJ’s so popular with OST albums is because it’s so hard to see them on TV. It helps promote the drama because any song released by JYJ sparks massive fan interest,” the official added.

Junsu is making his drama debut in a cameo role for the August 6th episode of SBS drama “Scent of a Woman.” Jaejoong is currently in SBS “Protect the Boss” that has recorded impressive TV ratings in the first two episodes this week. Yoochun has already starred in popular dramas such as MBC “Miss Ripley” and KBS “Sung Kyun Kwan Scandal.”
