I signed up! Hopefully I can get in and into a late enough spot that I'll be able to perform. (And hopefully I'll be able to learn my songs well enough by then...)
I have no qualms about talking about my songs, mostly because no one will know them anyway, haha. My prelims song is Kuchibashi ni Cherry, and my finals round song is Ashinaga no Salvador, both by EGO WRAPPIN'.
As for dancing, some people dance, some people just stand there nervously. I prefer to do something in between, since I don't really do songs conducive to -dancing-, per se, but I like to -perform-, you know? I'm not great at it and don't pretend to be, but it's so much better than just standing there and staring, right? Maybe I'll do some basic foot movements to the beat, I have a tendency to move my hands while I sing (it helps me hit high notes and draw out notes, alright?), and maybe I'd even get the audience to clap along during an instrumental, depending on the song. So really, it's about making yourself as entertaining as possible to watch while still fitting the song. I'm sure that a full-on dance number that augments great singing wouldn't hurt your score. ;P
