It's the big 4-0 for Brad Paisley on Oct. 28, 2012. The country singer has already put together a career to envy, and as his two boys grow older, there promises to be a treasure trove of new experiences for him to write about.

This fall, Paisley released 'Southern Comfort Zone,' a new song from an upcoming album expected to be available in the spring. As he's grown, every song has felt more and more important. In many ways, this West Virginian has become the voice of country music.
