Why is Ayu never mentioned in American magazines?

[ayu_ready?]

in Russia we have comp games mag called "Gameland"
so, it has a section called Banzai!
it's about j-culture
they mention anime a lot and write reviews,
but also has HQ clips of j-artists in every DVD they release!
I dl many Ayumi and others PVs here
but, anyway, we don't have a mag with her too!
[we don't have mags about j-culture at all!]
I remember sghe was mentioned in one mag,
but they gave such a bad review and wrote that she didn't have voice, style and music at all!
so, anyhow, I'm even happy she's not in our mags!
