The soundtrack to Frozen is No. 1 again this week, with 133,000 albums sold (presumably because all the children have already worn out their first copy). Meanwhile, it only took 29,000 albums — of Pharrell’s eminently listenable G I R L — to land the second spot on this week’s Billboard “200.” That’s the lowest No. 2 sales figure in the Soundscan era. So … prepare for an album of “Let It Go” remixes, coming soon to minivans near you.
