The members asked Mark how he came up with the rap segment for "Joy", in which he wrote himself.

Hearing this, Mark commented, "'Joy' is a combination of songs that have already been released.� Since the original tracks carry a bright tune, I wanted to do the same for this track as well.� I tried my best to portray a similar mood."

Meanwhile, NCT Dream's 'Joy' is a unique blend of popular Christmas carol "Jingle Bells" and "Joy to the World" with a fast tempo and energetic vibe.
