Reception Billboard's Tamar Herman praised the album and the title single, "While maintaining his typical croons, Zion.T refreshed his sound on "Your Song" with the lively piano-based melody...the singer’s latest is a refreshing, poppish update to his sonic style. With snapping, playful strings and a rock-tinged chorus, "Your Song" is a tightly produced track that complements Zion.T’s lush vocals." The song "Complex" featuring G-Dragon was selected by Apple Music 'Best of the Week'.
