It looks like there are many who have and "Others" option in mind. Me included too, because where's Tommy?
Out of your choices though, I'd pick Hikki and Ringo. Hikki because her song-writing skills have really come on leaps and bounds over the years, and Ringo because she's one of the most innovative, provocative and enigmatic artists in Japan.
And no, I'm not being partial to Toshiba-EMI either. I'd take Sony anytime.
