“Nobody wants to listen to their grandpa’s music,” Blake Shelton once claimed on GMC’s “Backstory.”

The tracks in his eighth studio album, “Based on a True Story,” are certainly not “old geezer” country. While the songs are undeniably catchy, the subject matter is nothing new.

The album’s first track, “Boys ‘Round Here” crassly encompasses every country stereotype imaginable. The first single, “Sure Be Cool if You Did,” is decent but forgettable and generic.

Ironically, the album’s strongest track, “Grandaddy’s Gun,” has a sound reminiscent of old-time country. The worst thing about this album is the obvious use of auto-tune in tracks like “Small Town Big Time.”

Shelton’s gravelly drawl certainly doesn’t need it. Overall, “Based on a True Story” has a few good moments, but if you’re craving some country, ignore Shelton’s words and give “grandpa’s music” a chance.
