K-pop boy group EXO has sold more than 1 million copies of its eighth studio album, "REVERXE," the group's agency SM Entertainment said Thursday. It became the band's eighth album to hit the 1 million mark since its 2013 first studio album, "XOXO." The new album reached No. 1 on iTunes' Top Albums chart in 48 countries and regions around the world upon its release Jan. 19. EXO will launch its sixth concert tour at KSPO Dome in southern Seoul from April 10 to 12, performing tracks from the album for local fans before heading overseas.
