After being forced to halt promotions for "Bubble Pop!" last week, HyunA made a swift return to the stage with her follow-up track, "Just Follow", on this week's episode of 'M! Countdown'! The track received high praise for its strong hip-hop beat, as well as an addictive melody that highlights HyunA's unique rapping skills. The song also features verses from rapper/songwriter Dok2, but instead of Dok2, Block B's Zico will perform on stage with HyunA for all music shows this week. Zico has also written his very own lyrics for his featuring in the song. HyunA has worked tirelessly to make this follow-up track her own, and as far as her performances are concerned, she will show her a fans a much more serious and charismatic side to herself, contrasting with the cute and bubbly performances she put on for her title track, "Bubble Pop". Check out her follow-up stage below!
