Sheryl Crow believes that motherhood has made her music better.

The Grammy Award-winning artist - who has adopted sons Wyatt, three and Levi, two months - thinks because being a parent has "enriched" her life, her new experiences are reflected in her work.

She explained: "Motherhood in general changes your life. Your life informs your art and for me it's just made my life so enriched. I've loved every minute of it."

The 48-year-old singer - who battled breast cancer in 2006 - admitted that her emotional state is the reason for the different sound of her new album.

Comparing her new record '100 Miles From Memphis' to her previous work, Sheryl said: "My last album had an urgency to it. I had a new baby Wyatt, I'd been through breast cancer and I had been through a bad break-up and I felt there was so much to write about.

"With this record I was coming from a much more emotional place. The idea of writing about desire and longing which is what soul music is typically known for, was where I was coming from".
