For the first time since November, five of the top 10 albums on The Billboard 200 this week are debuts. The strongest of these, the late Notorious B.I.G.'s "Greatest Hits," bows at No. 1, selling 99,000 copies in the United States, according to Nielsen SoundScan. The Bad Boy release is the rapper's third chart-topper, his second posthumously, and features two previously unreleased tracks, "Running Your Mouth" and "Want That Old Thing Back."
