As much I'm a big fan of hers, I must admit that I can understand why plenty of people are completely put off by her voice.
I really like "unique" vocal talents, but I just can't stand hitomi's song "BLADE RUNNER". it's bit a bit much even for me, her voice is just too screechy and the chorus is just really grating my nerves with it's composition/arragement even ignoring the vocals.
I just find hitomi's voice to be really expressive though, I think her nasal sound brings emotion into the songs. to me she sounds very unique in a good way
