While her strength was in TV shows and commercials, Eri had a few hit singles, her biggest one being "AB Complex". Now this is one great song! If someone asked me for an example of Japanese teeny pop, this would be one of the first tunes I'd play! Very cute and jumpy! In this song, Eri proudly states that her boyfriend is an "AB" bloodtype. Are they running out of things to sing about in Japan?
