This is one of my Favorit songs Von CircusP, EmpathP, and that uses SF-A2 Miki. The English is really great for an advanced Japanese voice bank. Only a veteran tuner can pull that off. The art is kinda wonky though.
This is my Favorit song using Tohoku Zunko, one of my Favorit Maika songs, one of my Favorit Hatsune Miku songs, and one of my Favorit CircusP songs. This song is freaking awesome.
This is one of my Favorit CircusP songs as well as one of my Favorit SF-A2 Miki songs. It may not sound like it, but this song is extremely deep and well-written. Some very valid hypotheses can be found in the comments.
This is my third Favorit 40meterP song. It's unique and iconic within in the industry as far as I can tell. It's also one of my Favorit songs featuring Hatsune Miku.
