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".
