Was RAINBOW the first album Ayu began using English?

[Aga-chan]

^The English part in "Close to you" is sung by the background singers at the end of the song.
Around half of the songs in "RAINBOW" include English parts. Like the "WE WI~SH" or "eve-ry-where~ nowhere" during the choruses of "WE WISH" and "everywhere nowhere" respectively. But those parts aren't mentioned in the lyrics. (Just like the English part in "forgiveness".)
