WEEKLY MARKETSHARE: If you’ve been paying attention, you don’t need to look at the above chart to know that Columbia rules the roost in this week’s new-release marketshare sweepstakes, thanks to the latest effort from a certain pair of helmeted Frenchmen. Daft Punk share the accolades for their biggest debut by a kilometer with Rob Stringer and Ashley Newton, who signed the duo, as well as Joel Klaiman and Scott Greer, who expertly stirred the pot of anticipation. From haute cuisine we go to biscuits and gravy, as Mike Dungan’s UMG Nashville continues on its roll, with no less than seven Top 50 entries—six of them on Capitol Nashville, remarkably enough, led by #2 Darius Rucker. Consult our sales chart and have fun connecting the dots with the rest of the Top 10 label groups. (5/29a)
