- Hotel Deluna OST, Punch&Monday Kiz→10cm → Taeyeon... Check-in at the top of the music chart. Welcome to OST.

Taeyeon, the "Hotel Deluna" and the OST's "The Poetry of Yourself" dominated the music charts.

After two years and six months since "I'll Go to You like the First Snow" by OST Ailee in January 2017, OST once again topped the music charts with its song titled "The Poetry of Yourself". 

OST is expected to revitalize the music charts like an iron fist.

The poem "Yourself" is a combination of delicate piano melody and refined tones unique to Taeyeon, which not only exudes mysterious charm but also adds affection to the drama's atmosphere.

The previously unveiled "Hotel Deluna" OST's 10-centimeter "Liberate on My Shoulder" and "Another Day" by Punch&Monday Kiz also settle at the top of the music charts, giving a preview of the OST syndrome.

The drama "Hotel Deluna" OST was produced by hit maker Song Dong-Woon, who produced "It's OK. It's Love," "Lovers of the Moon" and "Descendants of the Sun," "I'll Come to You like the First Snow," "Stay With Me," "Beautiful" and "I Miss You."

The "Hotel Deluna" OST, which is joined by the music powerhouses who believe and listen to it, and the nation's top OST producer Song Dong-woon, is causing perceptual changes in the music charts, and the lineup of singers to be unveiled in the future is drawing attention.

Meanwhile, the "Hotel Deluna" OST, which Taeyeon participated in following Punch&Monday Kiz, 10cm, is available through various music sites.
