8. Vocaloids can be tuned to be extremely lifelike and natural. However, Vocaloids will always struggle with two things: atmosphere and non-clean vocals. So I think that with the catchy arrangement, this song Corona has potential for nonstop looping. I just need to wait for Sekihan to cover it (he will cover it, he has to cover it, and it will be awesome).

11. Luka isn't particularly realistic here, but I find that I don't mind. The rearrangement sounds fantastic, the synthesised voice is not distracting, and the both illustration and PV are so cute!
