JAY-Z'S 'EMPIRE' CONTINUES TO RULE: Single featuring Alicia Keys remains at No. 1.

       The track enjoyed a 10.4 million bump in radio spins, second only to Ke$ha's 12 million listener spike for "Tik Tok," which takes the Airplay Gainer award as it rises 10-5, Billboard reported.      

       Lady Gaga's "Bad Romance" leaped from No. 11 to the second rung of the singles chart, joining her "Paparazzi" in the top 10. Also moving into the top 10, from No. 12 to No. 7, was French DJ/Producer David Guetta, with vocal help from Akon, on "Sexy Chick."      

       Other notable debuts included four more tracks from the cast of the TV series "Glee" and three tracks from teen heartthrob Justin Bieber. With "Down to Earth" (No. 79), "Bigger" (No. 94) and "First Dance" featuring his mentor Usher (No. 99), Bieber has now charted with all seven songs from his debut EP, "My World." That set opened at No. 7 on the Billboard 200.
