"Hold Still" is an emotional pop song about the feeling of being blindsided and left motionless by a sudden heartbreak. The track features an infectious, dance-driven groove that contrasts with its vulnerable lyrics about being in a state of emotional limbo after a relationship ends. Co-written by Mark, the song uses vivid metaphors like tasting blood on someone's name to express the lingering emotional aftermath of love and betrayal, serving as a pre-release single for his upcoming EP.
