Fred Bronson reports on the chart accomplishments of Eminem, B2K and P. Diddy, "Chicago," and R.Kelly.

8 MILES DOWN: After a 12-week reign atop Billboard's Hot 100, Eminem's "Lose Yourself" (Shady/Interscope) makes a dramatic drop, down to No. 9. It's the biggest fall from No. 1 in exactly 14 years. The week of Feb. 4, 1989, Phil Collins' "Two Hearts," from the "Buster" soundtrack, collapsed 1-10.

Since "Two Hearts," four songs have plunged 1-8: "Vision of Love" by Mariah Carey, "Coming Out of the Dark" by Gloria Estefan, "Gettin' Jiggy Wit It" by Will Smith, and "Maria, Maria" by Santana featuring the Product G&B.

BUMPED UP: Succeeding Eminem's "Lose Yourself" in pole position on the Hot 100 is "Bump, Bump, Bump" (T.U.G./Epic) by B2K & P. Diddy. It's the first chart-topper for the youthful members of B2K, and the fourth for Diddy, a.k.a. Sean Combs. It's Combs' first No. 1 hit in five years and five months. In the summer of 1997, "Mo Money Mo Problems" by the Notorious B.I.G. featuring Puff Daddy & Mase topped the chart for two weeks. Combs' other two No. 1 singles were "Can't Nobody Hold Me Down" and "I'll Be Missing You." Both were also hits in 1997.

ROXIE CHARTS: There have been at least three "Chicago" cast albums -- the original 1975 production starring Gwen Verdon and Chita Rivera; the Broadway revival starring Ann Reinking and Bebe Neuwirth; and the London cast album, starring Ruthie Henshall and Ute Lemper. But many people feel the movie soundtrack outshines them all. That's certainly true when it comes to the Billboard album chart. The Golden Globed-musical, which may be on its way to Oscar victories, has a soundtrack that blasts onto The Billboard 200 at No. 4. The Epic release thus bests the chart performances of the Broadway album, which peaked at No. 73, and the revival, which reached No. 131. The London cast album did not chart in the U.S.

"Chicago" is one of only three soundtrack albums that are movie adaptations of Broadway musicals to make the top five of The Billboard 200 in the last 25 years. "Grease" was No. 1 for 12 non-consecutive weeks, starting in July 1978, and "Evita" went to No. 2 in 1997.

On Billboard's Top Soundtracks chart, "Chicago" debuts at No. 1, displacing "8 Mile" after an 11 week reign.

TWO OUT OF THREE AIN'T BAD: Some weeks you just hope for some glimmer of good news. And we have some for embattled R&B star R. Kelly. On the Hot R&B/Hip-Hop Singles & Tracks chart, Kelly is the sole writer and producer of two of the top three titles. His own song, "Ignition" (Jive), rises 3-2, while his production of his composition "Bump, Bump, Bump" (T.U.G./Epic), recorded by B2K and P. Diddy, slides 2-3. The No. 1 spot is held by the woman Kelly was once married to, the late Aaliyah. "Miss You" (Blackground) is No. 1 for the second week.
