Have you ever listened to the high pitched voices on anime? It's much different from high pitched voices in American cartoons. The Japanese and Chinese music that I've listened to from my friends also contains men with high pitched voices. There's this group called puffy ami yumi (can't remember if I spelled that right).
You can listen to their music here:

But there is also a lot of high pitched voices in the netherlands
or wherever the group 'Within Temptation' is from. If you like high pitched voices and angst, you might like 'Ice Queen' or ('Snow Queen') by them.
You can download ice queen here:

There was this band with semi high voices called the murmurs in North America in 1995. My sister liked them. I liked them too but I would never have known about them had she not been listening to them. They were never widely known. One was a lesbian and the two girls were best friends. One had rainbow colored hair.

They were kinda lesbians or came across that way. One of the lead singers was definitely a lesbian. They have this new group called gush. More info can be found at:

Oh, this also reminds me of my friend Taeko from boarding school who would always talk in a really high pitched voice with Sue and her other friends. It was really funny how she said my name.
The closeness of Japanese school girls is also shown in a lot, a lot of Japanese anime (directed at kids) especially around the age of 14.
So these are some of the reasons why tatu is probably doing better over there.
