Jason Aldean - 9

2019 release. After almost 15 years at the top of his format, reigning ACM Artist of the Decade, Jason Aldean has seen trends come and go. He's helped bring a few out of the shadows, like a country-music Columbus making the mainstream's first contact with hard rock, hip-hop and R&B. But after all that time, he continues to hold his ground making modern albums with an old-school soul. "Early on, I always thought if we ever got to make nine albums, I'm going to call it 9. It was my baseball number growing up, and it's just kind of always been my lucky number," explains Aldean. "I remember cutting the first album and thinking 'that's forever away,' and now here we are. I don't know, it's really special we made it this far - so, it's more for me than anybody else - but, it means a lot."
