2PM's Taecyeon had only positive things to say after watching a fan cam of MONSTA X's cover performance of his group's 2009 hit single "Heartbeat." MONSTA X performed the song as a special stage for the recent 'Music Bank in Hong Kong' concert.
The rapper took to his personal Twitter account to share a video of the performance, commenting: "You seemed to have worked hard. It was really awesome." In a later tweet, he joked, "If junior idols keep tearing it up like that, do I have to do the same when we do our comeback tour?"
In response, MONSTA X's Shownu sent a message of gratitude, writing: "Thank you for enjoying it. Keep watching us in the future too, Hyung-nim."
