Keith Urban's getting 'High' with his new album

Keith Urban is aiming High with his latest album.

The country superstar announced Friday that his forthcoming album, High -- his first in nearly four years -- will drop Sept. 20.

"What makes you high can mean whatever you want it to mean," Keith said in a press release about the album title's ambiguity. "It might be physical, spiritual, herbal, meditative, chemical or musical, but it's definitely a place of utopia."

"For me it's my family, my friends, and this rollercoaster musical journey I'm on," he added. "Playing guitar, writing songs and the place where I feel high -- playing live. Every night I get a chance to bring an energy and a release to people."

Accompanying the announcement, Keith dropped the fourth track from the album, a song titled "Wildside." It follows previous releases "Straight Line," "Go Home W U (with Lainey Wilson)" and "Messed Up As Me."

Here's the complete track listing for High:

"Blue Sky"
"Straight Line"
"Messed Up As Me"
"Wildside"
"Go Home W U (with Lainey Wilson)
"Chuck Taylors"
"Daytona"
"Love Is Hard"
"Heart Like a Hometown"
