Do you know what the song silver girl was written about?

Hey anon, here are some quotes:

I penned ‘Silver Girl’ about Sheryl Crow… it’s an ode to a lady rock star who’s always on the road and has a very hard time having relationships and settling down. So it’s also totally about me.” (Uncut magazine)

“[Stevie wrote] Silver Girl, a semiautobiographical tune about ’‘being a silver girl lost in a high-tech world,” with a further verse about how “shadows move across her face, and you cannot see her soul unless she lets you.” (The Boston Globe)

“It’s an ode to the girl rock star inspired by Sheryl Crow, though it could be turned around and be about Avril Lavigne. I really feel Sheryl would have been much happier to be in my generation. She’s not a coward, and she says what she feels.” (USA Today)

“Silver Girl” is so classic you. It’s like a warm blanket.
“Thank you. Thank you little Sheryl Crow for inspiring me to write that.”
“The first couple of lines are definitely about Sheryl. And when I thought about writing a whole song to this poem I had called “Silver Girl,” I thought, ‘Well, this whole song could be about Sheryl and also about all the rock and roll women, be they Norah Jones, Avril Lavigne, Michelle Branch, Stevie Nicks, Gwen Stefani, whoever.’ That song is about the great parts, and also the difficulties, of being rock-star women.“
What a nice burden.
Oh, yeah listen, I wouldn’t trade it for a second. I’m never going to be one of those people that’s going to say, ‘You know what, this is just such a hassle,’ because it is not a hassle. It’s incredible. My life is incredible. I am a wild adventurerer. My life is totally exciting and it changes everyday. If I had dreamed this, I could not have written this down any better.”

“I wrote it about Sheryl Crow, someone who in many ways would have been much happier being part of that musical generation from 1965 to 1975. That song is sort of saying that it’s harder to hold onto your integrity today. Sheryl’s amazing. She never wanted to be judged on how she looked or what she wore, but she’s been pulled into that–she’s had no choice. And luckily she’s gorgeous, because otherwise it would have been hard for her.
Sheryl Crow, of course, has been very open about her own admiration for you, and in fact, it’s something I hear from a lot of young women artists I interview–you and Madonna keep coming up as icons.
“Well, don’t you think that comes out of the songs? I’m certain that a 15-year-old could listen to “Silver Girl” and relate to it. And Madonna has the same thing. She writes incredible songs, which by the way she pulls out of the air. She is an amazing songwriter, besides being beautiful and challenging constantly”. 
(Interview magazine)

“That’s written about Sheryl Crow. In the song where it says, “She would have preferred the last generation,” Sheryl absolutely would’ve preferred to be my age and to have been in our generation and to have been in her own Fleetwood Mac, more than to be in this generation. We all love her and try to take her along with us because we know that. It was very fun when she came to record with Fleetwood Mac. Lindsey likes her a lot and Mick loves her and John loves her, and she’s one of our little adoptees. So the song is like an ode to the girl rock star, and ode to the question, “Is it possible to find somebody to love?” When you’re rich and famous, it’s very hard to find somebody. That’s not taking away the hope, but it is stating that it’s difficult. When Sheryl asked me, “Am I ever going to find anybody?” I say, “Well, who knows? If you want to attain a certain amount of fame, then you have to work all the time, which is what you do. And you don’t hang out very much, you are on the move. You’re in New York, you’re in L.A., you’re in Switzerland, you’re in Vietnam, like a willow wisp. So it kind of depends on what you want to do.” I kind of made a choice when I was Sheryl’s age, when I was 40, that I didn’t really want to be tied down. There are many times during my life that I could’ve been married and I could’ve had children, and I made the decision to not do it. So I don’t know, with her; the only advice I can say is that “You live in the same realm of romantic possibility that I do.” (Performing Songwriter magazine)
