Breakthrough Korean Version Nightcore

Original Song: "BREAKTHROUGH (Korean Version)" by TWICE. You can find this and other Nightcore songs on my channel, and also on the “Our Favorite Nightcore Songs” playlist for other Nightcore songs! Check out the "Our Favorite Nightcore Songs" playlist on my channel! Nightcore is sped-up high-pitched music. Nightcore music comes from original songs; they just speed it up and it sounds different. I once read that it was to avoid copyright. This video is sped up by 1.25x from the original, as well as a pitch shift.
