Can you hear that noise? That steadily increasing thud-thud-thud-thud? Why, it's the sound of Americans running to record stores to buy Michael Jackson's Dangerous. In the past four weeks, the album has gone from No. 88 to 41 to 26 to 12. And next week the album will almost certainly return to the top 10, since the full impact of his Oprah Winfrey confessional has yet to be felt. Meanwhile, on the chart of old-but-steady-selling pop-catalog albums, Thriller is also making a strong comeback. As the thundering footsteps grow ever more deafening, let's hope that Mickey Jax doesn't perceive them as a rhythm, because we all know how grabby he can get. LAST POP ALBUMS WEEKS ON WEEK CHART
