Stevie only writing ONE song in 18 months?

[RockALittle250]

From the time we have all read that statement, I have found it hard to believe. Going back, and looking at past news articles, I have found this one, that i'm sure we all remember. http://www.rgj.com/news/stories/html.../28/105209.php. This statement in the article is the thing that really caught my eye...and one more thing, the article was published in late July of this year, 4 months ago.

Like many albums released in the summer of 2001, “Trouble in Shangri-La” got lost in the madness that was the aftermath of the Sept. 11 terrorist attacks. Nicks said she is unsure if she’ll release another solo record.
“I really don’t know what to do,” she said. “I’m totally writing. I could go into the studio tomorrow and start a solo record. I think I get better as a writer every day because I work on it constantly. So it’s not like I couldn’t do it, but ...”

So if she is "totally writing" why is she saying that she has only written 1 song in the past eighteen months? It just doesn't make any sense to me.
