Garth Brooks' Blame It All on My Roots: Five Decades of Influences climbs to No. 1 on the Billboard albums chart this week. The eight-disc boxed set, available exclusively through Walmart, sold 146,000 copies in its second week of release, following a debut week of 164,000 according to Nielsen SoundScan.

It's the ninth No. 1 album of Brooks' career and the second package with more than two discs to top the chart since Led Zeppelin's How the West Was Won live set in 2003, according to Billboard. Blame It All on My Roots contains eight discs — six audio and two DVDs.

Brooks' boxed set, released on Thanksgiving Day, had fewer than four days of sale its first week. Look for news of the singer's 2014 world tour, announced Monday on Good Morning America, to keep sales up for next week's chart.

Last week's chart-topper, One Direction's Midnight Memories, finds itself in Billboard's No. 2 slot this week, followed by Kelly Clarkson's Wrapped in Red.

Britney Spears has the week's top chart debut, as Britney Jean enters at No. 4, selling 107,000.
