“Go Harder” is a slick, high-energy anthem by Musa Keys, featuring Optimist Music ZA, that blends motivational messaging with polished, groove-heavy Afro-tech and Amapiano elements. It’s a celebration of ambition and forward motion — a track built not just for the dancefloor, but for the grind, the hustle, and the moment you decide not to quit.
Musa Keys and Murumba Pitch recently appeared on Cina.
From the moment the beat drops, Go Harder establishes a confident, forward-moving energy. Musa Keys flexes his production versatility here — moving slightly away from his softer, romantic Amapiano tones and leaning into a sharper, club-ready Afro-electronic space. The percussion is tight, layered with bouncy log drums, clean claps, and atmospheric synths that build tension and release. It’s a beat that keeps your feet moving and your focus locked in.
Optimist Music ZA delivers a melodic vocal performance that’s both catchy and commanding. His lyrics center on perseverance, progress, and inner drive, serving as both a chant and a mindset. There’s an empowering tone to his delivery — not aggressive, but resolute. He sings not just for the vibe, but to inspire. His name feels well-earned here: the voice is motivating, forward-facing, and optimistic in message.
The chorus is simple and effective — “Go Harder” repeated in a rhythmic mantra-like loop that becomes more addictive with each listen. It sticks in your mind, pushing you to move, dance, or push through whatever obstacle you’re facing.
