IU and four-member male vocal group Brown Eyed Soul (Jung Yeop, Naul, Young Jun and Sung Hoon) are dividing and conquering major music charts with their new releases.

“Modern Times – Epilogue” is a repackaged version of IU’s third album, and contains two new songs, her self-composed title song, “Friday” and new song “Crayon” (which was featured on her currently airing drama “Beautiful Man”). The album was released on December 20 at noon.

“Fridayy” topped Melon, Olleh Music, Bugs and Genie charts within an hour after its release. The song itself has a swing rhythm and addictive melody; its lyrics straightforwardly express a girl’s fluttering heart before a date. IU took on writing and composing the song, roping in History’s Jang Yi Jeong for a featuring on the song. The music video for “Friday” features a kiss scene with top model Jang Ki Yong.

Brown Eyed Soul released their new song, “You,” on December 19, topping Soribada, Monkey3, Naver Music and Daum Music real-time charts the same day, and continuing to keep their number one spot a day after release.

“You” is an R&B ballad written by Brown Eye Soul, and is part of a three-song album, “Thank Your Soul.” It features the strong vocals of Naul and the distinct voices of the other three members.
