I'm sure the affectations are natural, but her songs still definitely incorporate some digital work, too. More for effects than on her voice, though, I would imagine.
Especially for her genre, it's appropriate to use those effects. Techno, dance mix, or whatever people call it nowadays. It's just when she sings live or acoustic, I have to admit that she can actually sing for reals, but her music is just annoying. So she's technically talented, but not very creative. Or too creative, depending on how you look at it.
But yeah, how about them tracks in TSL. Pretty cool. I was actually playing guitar the other day, and had found a progression that sounded like it belonged in KQ. Somewhat reminiscent of the song playing in the intro of KQVI.
