English words in Ayu songs: article?

[Larien]

I'm writing a paper for a sociology/anthropology course ("Cultural Politics in East Asia") about the use of English words in Japanese music, and I naturally want to include Ayu in here somewhere.
I need help though! I believe I remember seeing an article or a review that mentioned, at least in brief, Ayu's use of English lyrics/song titles, especially since the Rainbow era. Would anyone know of this?


P.S. Since I'm already asking, does anyone happen to have a link to that article about the prime minister or some other senior Japanese official holding up a magazine cover with Ayu's face on it? Thank you!!
