Doug Morris’ almighty Universal Music Group continues its historic run at 30% marketshare, driven by #1 and #2 labels Island Def Jam and Interscope Geffen A&M. UMG currently sports a whopping 29% share, up 1% from a month ago. That’s a healthy 11%-plus lead over #2 BMG at 17.6%, down .5%. Also down are WMG at 15%, Sony at 14.9% and EMI at 7.9%.

At the label level, top-ranked IDJ’s already-ferocious 2002 run continues, led by current chart-toppers Ashanti, Cam’ron, Musiq and, of course the Spider-Man soundtrack, which IDJ shares with Columbia. IDJ’s 9.3% now leads #2 IGA’s 8.5% by less than one point, IGA having just gotten a monumental boost from The Eminem Show, which has moved 2.25 million in two weeks. Last month, IDJ led IGA by over 1.5%.

Columbia and Epic are tied with 6.8% apiece, with Marc Anthony and Celine Dion their Top 10 mainstays, respectively. But watch out for the new Korn, which will chart next week and contend for #1. Following the venerable Sony brands are Warner Bros. at 6.3% and Arista at 4.2%. #7 Universal/Motown and #8 Atlantic are neck-and-neck at 3.9% and 3.8%, while RCA Nashville and Virgin round out the Top 10 at 3.0% and 2.7%, respectively.

Those numbers sure are purdy, but with six more months to go in the calendar year, they’re sure to change some, too. Stay tuned.
