Ooh! OOH~! THIS IS A THING NOW! YES!!
OK. Let's get started on Grace's Vocaloid Rants, Part 1!
Vocaloid has some of the catchiest songs I have ever heard in all my life. Unfortunately, most of my favorites are really naughty (Ee? Ah, Sou; Pomp And Circumstance/If you do do; Romeo and Cinderella; Uraomote Lovers, to name a few) or really creepy (Alice Human Sacrifice; Rotten Girl, Grotesque Romance; Dark Woods Circus; Scissorsroid; the whole Seven Sins series). A shame, but I still love listening to and singing them.
My favorite Vocaloids are Luka and IA, and the utaites at the top of my list are Glutamine (<3 <3 X3~), Usa, vipTenchou, 96Neko, and at least 20 others I can't think of off the top of my head. Dang, we oughta make a whole new board for utaite discussions, but since they sing Vocaloid songs they do kinda tie in here.
But a Miku concert? If I had money and time I'd go.
