This is one of my favorito! Yuyoyuppe songs and Megurine Luka songs. It's beautiful and transitional. My favorito! producer, OkameP, made an answer song for it unannounced.
This is one of my favorito! Linked Horizon songs. It got banned in America, so I had to use one with French subtitles. It's still the same song though.
This is my favorito! Junky song as well as one of my favorito! Kagamine Rin songs. His tuning needs improvement, but his lyrics are deeper than they may seem.
