Another Day, Another Song~ Let's Go!
Namae No Nai Kaibutsu by EGOIST (Psycho-pass Ending 1)
Put one of the best psychological animes out there, one of the best anime songs, and a great band together, you get this masterpiece. With a feel of soft-techno, a rock-style background, a touch of classical music and an amazing vocalist to top it all off. Not only is the anime amazing but, personally, I got even more hyped every time this song started playing, it makes the anime that much more enjoyable!
Original Video which is even better, capturing the creepiness + awesomeness of the anime just right.
Close Your Eyes and Listen!~
