Weekly marketshare

YOUR WEEKLY MARKETSHARE SCORECARD: Most weeks, a #1 album approaching 300k units will get you the W, and this week was no exception, as Katy Perry quarterbacked CMG to a decisive victory, with PRISM selling 244k more than the #2 entry, Miley Cyrus’ Bangerz. Interestingly, even with the Tower team’s towering tally, the top five label groups YTD are the top five of the latest sales week. CMG is a shoo-in to retain its position next week by way of the company’s affiliation with Merge’s Arcade Fire, whose Reflektor will fight it out with PRISM for #1—and that’s a win-win situation for Steve Barnett’s squad.
