Oh, this would be fun! D:
It'd be nice to go to Family Karaoke Studio in Beaverton, since it has a handful of Vocaloid songs,
but I don't think it's enough to spend a couple hours singing the same 10 songs over and over ^^;;
Might be worth a shot though, I'm not sure, haha.
If this happens, I may be in as Miku :3
