I did listen to the album. I didn’t like it. It sounded kinda generic. Bad-generic to me. How-Low-Hello does have its good songs, but for the most, it’s uninteresting to me. Not to mention the irrelevancy of How-Low-Hello in the anime. Maybe I just didn’t like the repetitive chorus that seemed/felt the same to my ears
And Oppai ! it’s the “end of the world” for humanity with perverted senses from Kotarou
