I WANT to say that this is a good idea, but even without bias there's one glaring problem here - Yukiho, because of her VA switch. Here we go and First Stage never received Asakura solos, and most of the other listed songs you judged from only have solo opportunities from one VA or the other (and I'm aware that there are solo parts of group songs you could judge from, but that muddies your goal).
Yeah, I definitely agree. I actually tested this by listening to both of their versions of Tonari ni, and I found that I rated Asakura's higher, but only by half a point. I like both of their voices, but they both have their own strengths. I thought about changing the list to include either one or the other, but decided against it since I didn't want to take this
too seriously. Yeah I want to be unbiased, but I'm still just trying to have a bit of fun and discover what I actually think. It's not like it's government research

Also, am I wrong for thinking the First Stage from the Shiny Festa games was done by Asakura? I didn't use it because I didn't realize at the time, but now I guess I could have. Is that what you were mentioning?
Not sure what I feel about this as I'm not a fan of these bias-type threads, especially this one. Opinions are nice, but with the way it's written... not so much. I think you better off removing the scores and just tell it in words. Let's hope that this doesn't turn into a flame war, but that shouldn't be a problem considering our records here. I don't want to deal with... certain people here.
I definitely see your point, but it's not like this is the first thread of its kind. I know of at least three other threads like this, some of which have things said about the idols that are far worse than this, and they never turned into flame wars. You've already kinda said that though.
I'll remove the scores because a flame war is not my intention, but then I'll kinda feel like this topic will be pointless because I could have posted this in the topic already made. The scores were what made me decide to make this its own topic after all.
I hope this doesn't sound like I'm dismissing your opinion, because that's really not what I want at all.
As for being biased, I too thought I would be too biased for this to work. If I did feel it was, I wouldn't have posted it at all. But I was actually surprised at how much I liked some of their voices, and some of them ended up doing much better than I expected.
