While fans knew Jonghyun as a singer with a knack for ballads, the 24-year-old recently expressed his desire to branch out from the ballad style and eyed genres and collaborators he was personally inspired by for his eclectic EP that ranges from booming R&B to slick disco dance-pop. In addition to Zion.T and IRON, Base also features Korean rock singer-songwriter Younha.
Base marks the first solo No. 1 for any SHINee member on a Billboard chart, but two of his band mates have also done well on their own too.
Last summer, SHINee's Taemin made his solo debut with his Ace: The First Mini Album EP. The set peaked at No. 2 on World Albums on the chart dated Sept. 6, 2014 while the music video to its lead single, "Danger," was the most viewed K-pop video in America in its release month.
