NEW YORK (CNN) -- Annie Lennox has incredible eyes.

Annie Lennox's new album, a best-of, will be her last with Sony.

They're a translucent blue-green, both kind and inviting in one glance, then piercing and all-knowing in another. At 54, Lennox's orbs are as captivating today as they were when they stared at us from under that fiery orange crew cut in the music video for the Eurythmics hit "Sweet Dreams (Are Made of This)."

That was 1983. Yes, Lennox's Eurythmics days seem like a lifetime ago for the Scotland-born singer-songwriter, especially when you consider the successful solo career she's enjoyed since her partnership with Dave Stewart.

It's that body of work -- songs like 'Why" and "No More 'I Love You's' " that are showcased on her newest album, "The Annie Lennox Collection." It's Lennox's fifth solo outing, and her final album with her record label of 30 years, Sony Music Entertainment.

"It's like a demarcation line in a way because there is that body of work to look back on in retrospect," says Lennox. "And the future is ahead of me and that's very interesting because I'm really not sure exactly what that's going to mean logistically ... how that's going to pan out. But I'm very excited about it because of Internet technology."  Watch Lennox talk about catharsis »

Lennox, who's won Grammys, BRIT Awards and an Academy Award (for co-writing "Into the West" from "The Lord of the Rings: The Return of the King"), says she's become somewhat of a voracious blogger, using her MySpace page and official Web site not only as a repository for her musical work, but also to lend a voice to her humanitarian efforts. In 2007, Lennox formed the SING Campaign, a nonprofit initiative to help fight the HIV pandemic in Africa.

The initiative has its own anthem, called "SING," which features vocals from Madonna and Celine Dion among others, and is included on Lennox's new album. She also recorded two new tracks to celebrate the release, one a cover of Irish band Ash's hit song "Shining Light."

"It's one of those incredible anthemic songs that just stay with you," she says. "It's like when you heard Jeff Buckley's version of Leonard Cohen's 'Hallelujah.' It's almost like a revelation when you hear it."

Lennox spoke to CNN about tapping into her inner divas to make those theatrical music videos, the pitfalls of fame and why she celebrates her naiveté.

CNN: Who is your "shining light"?

Annie Lennox: Ordinary people who don't necessarily have the spotlight shone on them, who do extraordinary things. Those people always inspire me. A lot of people that are working in nongovernmental organizations inspire me very much, because I think those people are really risking life and limb to make a difference to people's lives in really impossible circumstances. And they really give me the sense that if they can do that, I can do something, too.

CNN: How do you feel about where you are in life right now?

Lennox: Of course now I'm in that middle-age place, age-wise, and youth is no longer really something that I'm a part of anymore. And that started happening for me when I was about 40, to be honest with you. I had my kids and my focus went elsewhere. And I think I've changed so much through having children ... inside myself. It's been a kind of evolution and a maturity.

And that has informed the SING Campaign a lot, because my focus is really on women. ... I understand what it is for a woman to want to protect their children and give them the best they can. And so I identify with that. ... I can let go of some of the things I was maybe focused on when I
