Garth Brooks continues to have the nation's top-selling country album with Blame It All on My Roots.

It's a multi-disc Walmart exclusive, and it's sold more than 170,000 copies -- a 17 percent increase over last week. Duck Dynasty: A Robertson Family Christmas holds steady at number-two, and Luke Bryan remains in the still-respectable third place with Crash My Party. Florida Georgia Line's Here's to the Good Times land in the number-four slot, up one from last week. Zac Brown Band's Dave Grohl Sessions Volume One rounds out the Top 5.
