Mm, I'm not sure if there's a particular song where I think it sounds more similar...
Anyway, here's a video with Skye Sweetnam:

Like I said maybe I'm delirious... but when I was listening to JUNGLE DANCE, it randomly occured to me "Wow... there's something so
western about her voice..." and couldn't figure out exaclty what it was. I think it sounds like Skye Sweetnam to me~ their voices have the same ammount of huskiness or something XD
