Rajat Singh, known by his stage name Zack Merci, is a 24-year-old music producer, composer, and sound engineer from India. Since diving into music production in 2016, Zack has been on a relentless journey of musical exploration, fearlessly experimenting across genres. Whether it's vibrant pop melodies, heavy Trap beats, high-energy Drum & Bass, EDM drops, or the even trying his hands on Dubstep, Zack's music refuses to be confined to any one style.
This versatility has earned him over 45 million streams across all platforms and a growing international fanbase.

Zack’s breakthrough came with his signing to NCS (NoCopyrightSounds), and he's since expanded his reach with releases on Kannibalen Records, Magic Records and many more. His tracks have also been charted globally, including #3 in Thailand, #5 in India, #6 in Taiwan, #17 in Belgium, and #21 in Australia on iTunes.

For me, music isn’t just about making sounds-it’s about connecting with people. I’m always looking for new ways to express myself and share something that resonates with my audience. Whether I’m creating something familiar or stepping into uncharted territory, I want my music to surprise and inspire listeners. That’s what keeps it fresh for me, and I hope it does the same for you.
