It has been revealed that IU will take part in the OST (Original Soundtrack) for the historical drama Queen Seon Duk. She will be singing a song called, "Araro", which will be the drama's ending title song. The music director of Queen Seon Duk recommended IU to participate in the OST because of her clear tone and her lyrical sensibility. This will be IU's first sageuk (historical drama) OST, so she took time to carefully understand and analyze the lyrics to the song before recording. IU commented, "I'm honored to take part in the OST", "Because this drama is receiving a lot of the nation's love, I worked harder on the recording to help support the drama", "I hope you will love the OST as much as the drama". In Korean, the Ara, in "Araro" stands for the ocean, which the lyrics metaphors Seon Duk's journey to become the queen of Silla. Queen Seon Duk is one of my favorite drama that I am currently watching. I will love IU I will definitely love the OST song as much as I like the drama. Stay tuned to the next episode and watch the credits at the end as this new ending title song will be playing.
