"The world's changed a lot in 20 years, but songs are pretty much about love or lost love," Jackson, 50, told The (Nashville) Tennessean. "And the rest of the stuff's just about life."
The "Here in the Real World" singer credited his relatively late start in the music industry at the age of 25 with his song-writing approach, the newspaper reported Sunday.
Jackson said prior to creating music, he had been married for several years and worked a variety of jobs, including construction worker and automobile salesman. He told The Tennessean those experiences helped him when creating his lyrics.
"I'd lived a lot of life before I got to Nashville, and that gave me a lot of files that I pull from still today," Jackson said.
