Lady Gaga is still dancing atop Billboard’s Hot 100 this week. Moving 201,000 downloads in one week, Gaga’s “Just Dance” featuring Colby O’Donis easily claimed the #1 spot on the Hot 100, shifting a total of 2.14 million downloads since its release in spring of 2008. Following closely behind Gaga’s hit, Beyonce’s “Single Ladies (Put A Ring On It)” lands at #2 on the Billboard Hot 100 chart, however, holds the #1 spot on the Billboard R&B/Hip Hop songs tally for a ninth week. In addition, Beyonce’s “Single Ladies” rose to #1 on the Hot 100 Airplay chart this week. In what Billboard is calling the most tightly contested battle for the top spot since N’Sync’s “Bye Bye Bye” finished ahead of Destiny’s Child’s “Say My Name,” Beyonce’s “Single Ladies” beat out T.I. by just 350,000 impressions for a total of 147.3 million listener impressions. Kanye West’s “Heartless” ends up being the week’s fastest growing track at radio as it jumps 5-3 while T.I.’s “Live Your Life” ascends 3-4. Taylor Swift (Love Story), Katy Perry (Hot N Cold), Jason Mraz (I’m Yours), Kevin Rudolf (Let It Rock), Britney Spears (Womanizer) and The All American Rejects (Gives You Hell) round out the top 10 respectively.
