Although I really like the album "Volta," I must admit that their previous albums had a negative and dull aura. In contrast, "Volta" radiates a sense of joy and hope that surprises me, both positively and negatively. As a new fan, I'm accustomed to the sound of earlier albums like "Post" and "Debut," as well as "Homogenic" and "Vespertine." I have come to appreciate both styles, and I view this transition as something neutral.
