The guys had already spent time in Los Angeles while filming their 2014 reality show American Hustle Life, an on-camera exploration of learning the roots of West Coast hip-hop, working with rap veterans like Warren G and Coolio. "We realized that things are quite harsh and hard -- everywhere, but especially in America," BTS' leader Rap Monster says at Billboard Studios in New York. "What Warren G and Coolio told us was that it comes from the heart, it's open to all kinds of people in the world. We don't need any prejudices for hip-hop. We should listen to the music of hip-hop by our hearts."
But the septet also have love for America's current girl group supreme Fifth Harmony, whose latest hit "Worth It" is No. 15 on the Billboard Hot 100 this week."When I first listened to this song, I thought, 'Wow, this is crazy. This is my new favorite,'" Rap Monster recalls of the time he shared the ladies' breakout smash on the band's Twitter account. "I really want to get to know about them and I think they're so good." How about a collaboration, 5H?
