What does closing with a cover like Mercury Blues tell you about how Jackson sees himself as a country artist?

He is a country artist that respects the tradition of country music, he helped usher in the neo traditional sound of the nineties, and he went out of his way throughout his career , to show support for the legends in the older generation, country music was built on covers songs, back in the day , everyone did everyone song

I enjoyed this one. It showed some breadth to his influences. He can do that classic rock vibe reasonably well. It has a tinge of Kenny Loggina. (I could see this on the Caddyshack soundtrack for some reason.)
