Keith Urban, 'Kiss a Girl' (Sessions)

Keith Urban is sticking to the musical formula that's resulted in more than 12 million albums sold, 19 Top Ten singles and countless die hard fans. He's just doing it now with an even bigger smile on his face. The 41-year-old country superstar's sixth studio album, 'Defying Gravity,' is full of the hook-laden, feel-good music that's garnered him so much success over the past decade. But this project is undoubtedly more euphoric, reflecting more than ever Urban's personal life.

It's that life outside of the studio and off of the tour bus where the Aussie crooner has found a greater sense of peace and happiness. But while Urban bears his heart on his musical sleeve, the husband to actress Nicole Kidman and dad to baby daughter Sunday is notoriously soft spoken about matters of the heart. He'd simply rather you come to your own conclusions by listening to his songs.
