Love plays a huge role in Ai Otsuka's music. Every album she released in the first decade of her career features that word—Love Punch, Love Cook, Love Letter, and so on—and it dominates the Osaka performer's upbeat brand of pop. She explores the emotion with both driving rock and jittery electronics. Her genre-hopping has also resulted in more dramatic ballads that amplify the dizzying quality in her sound. Love comes in many shapes and Otsuka has a song for every form.
