India, Feb. 11 -- A merican DJ-record producer Diplo has confirmed his involvement in Korean boy-band BTS' upcoming album Arirang, the group's first full-length release in nearly four years. Speaking to TMZ, Diplo described the album as "the craziest ever," adding, "It's going to be the biggest thing I've ever done. I'm so happy to be part of that culture. Honestly, the album is gonna shock the world." Describing the collaboration as a major career milestone, the 47-year-old said, "I feel so lucky. They're so hands-on, they're so creative. I can't believe it. They're funny as hell, they rap, they do everything,. They're the real deal," he said, offering special praise for BTS member Jung Kook's vocals, noting, "No AutoTune, perfect voice." He added, "Those are grown men. They're in their thirties, they've been in the army, they've lived life. They dance better than any of us, and they still smell really good." Following the album's release on March 20, BTS will embark on an 82-date world tour starting March 21. It will also include a live-streamed concert and a behind-the-scenes documentary. HTC...
