On the April 1 installment of 'Sugarman 2', the two idol groups showcased their talents by giving their renditions of some Korean songs that will forever remain as a classic.

MONSTA X covered the late Kim Sung Jae's mega-hit track "As I Told You" on this day. While maintaining the original, new jack swing style of the song, the boys were able to put their own spin into it by adding some new choreography and rap verses making it much more modern. 

Meanwhile, B1A4 sang the late Choi Jin Young (Sky)'s "Forever", an emotional ballad track. By mixing the original, heartfelt sound of "Forever" with Baro's signature rap style and the group's amazing vocal abilities, the song came alive once again to steal the hearts of all viewers and audience alike.
