Last week's No. 1, Kanye West's Yeezus, fell by 80%, dropping to No. 3 on the Billboard 200—the largest second-week percentage drop for a No. 1-debuting album in more than a year. It sold 65,000 in its sophomore frame, compared with last week's 327,000.
Comparatively, the average second-week drop for a No. 1-debuting album in 2013 is 69%. (West's last solo album, 2010's No. 1-bowing "My Beautiful Dark Twisted Fantasy," slid by 78% in its second week.)
No. 1 debuts that were particularly front-loaded in their first sales week this year were Yeezus, Bieber's Believe Acoustic (down 79% in week No. 2), Chris Tomlin's Burning Lights (down 78%) and Fall Out Boy's Save Rock and Roll (down 77%). On the other end of the spectrum, the smallest second-week erosion for a No. 1 bow belongs to Josh Groban's All That Echoes, which fell by just 50% in its second frame.
