"'Case of You' is a song about remembering those first few moments when you were falling in love," singer-songwriter Jenny Lea explained in a statement. "A snapshot of flirtation, infatuation, and living in the moment." Featuring beats by Mikey J Blige, the "collection of honeymoon-phase memories" is transformed into a moody cinematic journey scored by genre-bending electro-pop and R&B grooviness.
