I recognize that this thread is extra-old, but I thought I'd comment on it anyway. I LOVE Sowelu, the girl has such a pretty voice. I haven't listened to her in quite a while, but she was one of the first J-artists that I heard music from.
I love Sowelu's music too. I prefer her older stuff to some of her newer attempts. But I still like to listen to her. My favorite song I think has to be Rainbow. That song is just so great!
