As expected, alternative rocker Jack White scored his first-ever Billboard chart-topper last week as his solo debut "Blunderbuss" moved 138,000 units to top the Billboard 200 albums chart.  Despite reaching the top 10 on the chart seven times with his bands the White Stripes, Dead Weatherr and the Raconteurs, White never before achieved a No. 1.  Prior to "Blunderbuss," White's highest chart position had been with the Stripes' 2007 set "Icky Thump." which debuted at No. 2 with 223,000 sales in its first week of release, but the album never moved up from there.
