This week's KPOP COVER we bring to you Kpop's angelic voice, Hyorin from SISTAR covering Beyonce's Halo. The cover also fetured Yiruma, the famois world pianist from Korea. The collaboration started when Yiruma saw the video of Hyorin singing Halo in one concert before. This cover is such a beautiful one so enjoy it. Video credits to Naver.
