On September 20, 2023, Seventeen announced their plans to release their eleventh EP Seventeenth Heaven the following month through a 30-second video of a red festival wristband.

[11] The item was launched using spacecraft attached to a high-altitude balloon filled with hydrogen gas, ascending to over 113,000 feet, where it was filmed for over two hours for a four-second clip on the music video.

[15] Maria Sherman of the Associated Press praised the track, describing it as both a "sunshine-y pop single with bright brassy touches" and "a life-affirming sing-along so nice they put it on the album twice".

[16] In agreement, Hwang Ji-young of JoongAng Ilbo wrote that "God of Music" was a "festival-like song that lets you feel the energy of happiness that Seventeen talks about".

[17] Commending the song's addictive nature, Lee Min-ji from Newsen identified the onomatopoeic chorus as a captivating rhythm that "will make your shoulders shake even after just hearing it once".
