1. Am I taking the male part of Choose Me, then?
2. And which part of Primary Colors?
3. Hitotsu no Kimochi sounds fine. It's within my range.
4. Shining Star also sounds fine.
5. With You feat. Me sounds okay, from what I listened to.
6. Flyaway sounds fine, from what I listened to.
7. Follow the Nightingale sounds pretty, and the part I listened to was in my range. (Reminds me of Life Returns from Fire Emblem XD That has backwards Japanese.)
8. Cendrillon stretches me on both ends, but I can mostly manage Kaito (the only part I have any trouble with is the bridge - both with Kaito and Miku, the rest of the song I can alternate between them and still hit the notes just fine.) But with some practice I could probably hit Kaito's low notes, and MAYBE manage to hit Miku's high. But if the two of you are definitely singing together on it, then I won't worry to much about Cendrillon.
9. Happy Material sounds fine.
So I'd be happy to sing any of those! Or all of them. Whatever. Just let me know.
Um, just so you know, I don't know who's who on any of the parts. So you'll need to tell me which part's which. Ideally you could highlight (or something) the parts of the lyrics "my" part is since you're more familiar with the song, but that's troublesome, I know. So just say 'the second voice that sings' or something if there isn't a clear distinction, like obviously female and obviously male. Sorry I'm being a pain. XD
More songs... well, I know quite a bit of Vocaloid. I'm particularly fond of Mothy-P, though his songs may not be your style, and many of them don't have alternating parts.
I like some of the Hearts Grow songs, those are duets, and I think most of them are within my range. I would VERY MUCH LOVE to sing Sora. I've wanted to do a duet on that for years. The range isn't very demanding at all, and I even already have a lyrics sheet colored depending on who sings when. I believe I can find an instrumental track for it, too.

(From the sounds of it, we may be monopolizing the Karaoke room. XD)
Oh, um, just so you know, I'm a minor, and I'll still be a minor (if only by a month) during Kumoricon. So that limits my available hours in the convention.
