SEVENTEEN performs a medley of their biggest hits, including 'Very Nice,' 'CLAP,' 'Don't Wanna Cry,' 'Snap Shoot' and 'Left & Right,' plus a cover of Justin Bieber's 'Holy!' SEVENTEEN tells ET, "'Holy' has been on repeat for us ever since its release. It’s been stuck in our heads and we often found ourselves humming or singing along to it throughout the day as well. So naturally, when we got the chance to perform a short cover of a pop song during our ET medley, all of us came to choose 'Holy!' SEVENTEEN’s been working hard in the studio to bring new music your way. Stay tuned and keep an ear out for more from us this year!"
