Blake Shelton's 'She Wouldn't Be Gone' is the No. 1 song on the country charts for the second week in a row.

"I love to sing songs about regret and mistakes you make along the way," Shelton tells Dial-Global of his latest hit. "'She Wouldn't Be Gone' is extremely emotional and has a little different slant on things the guy could have done right along the way."

Though Shelton didn't write the song himself -- it was written by Jennifer Adan and Cory Batten -- he can certainly relate. He says he takes the lyrics to heart when it comes to romance.

"I think it takes men ... we have to have a wakeup call," he says. "We're pretty stupid sometimes [laughs] and sometimes it just takes to physically see what you've done in order to wake you up. And a warning just isn't enough a lot of the time. More often than not, you really have to make a huge mistake and have to live with it before you become a better person."
