Jo Dee Messina

There are many -- too many -- country stars who have had cancer or have been personally affected by it in some way.

Messina songs have a lot of attitude.

The singer admits that as a young artist, she was terrified that Brooks might cover her song, "Heads Carolina, Tails California."

"I spent my entire career, my entire life, glorifying myself," Messina says. "It's time for Him."

"I was by myself in a hotel room, and we were on a radio tour ..."

Some of its biggest stars -- yes, even the ones who sing drinking songs -- are sober.

On April 17, 2006, Messina ran the Boston Marathon ... and completed the race, even after injuring her knee.

Nothing beats a cool country soundtrack to crank up while you're exploring those wide-open spaces in your chosen mode of transportation.

April showers bring May flowers ... and some really good country songs about rain.

Despite her struggles, the singer says she's "filled with gratitude and joy."
