Fred Bronson reports on the latest chart feats of Pink Floyd, Linkin Park, and 50 Cent.

BOTH SIDES OF THE 'MOON': A casual glance at Billboard's Top Pop Catalog chart this week might cause a double-take: Pink Floyd's "Dark Side of the Moon" (Capitol) enters at No. 1, and is credited with one week on the chart. If that doesn't seem possible for the album that set the longevity record on this chart, look closer. The original release of "Dark Side of the Moon" slides 19-22 in its 1352nd cumulative week on the tally.

The new "Moon" at No. 1 is a 30th anniversary edition, issued in the Super Audio CD format, and has a separate catalog number. A vinyl LP of this anniversary edition will be issued April 22.

PARK'S PLACES: After the group's first two albums peaked at No. 2, Linkin Park collects its first No. 1 title on The Billboard 200. "Meteora" (Warner Bros.) beats out Celine Dion's "One Heart" (Epic) to take first place. "[Hybrid Theory]" and "[Reanimation]" both had to settle for second place.

Linkin Park tops two other Billboard charts this week. "Somewhere I Belong" moves 2-1 on the Modern Rock Tracks tally and 3-1 on the Mainstream Rock Tracks list. On the Modern chart, "Belong" is the act's second chart-topper, as its "In the End" had a five-week reign that began Dec. 22, 2001. On the Mainstream chart, "Belong" is the band's first No. 1. "Crawling" and "In the End" were Linkin Park's biggest Mainstream hits until now; both songs peaked at No. 3 in 2001.

'IN' TO SOMETHING GOOD: 50 Cent's "In Da Club" (G-Unit/Shady/Aftermath) is No. 1 on Billboard's Hot 100 for the sixth week. That makes it the longest-running chart-topper since labelmate Eminem ruled for 12 weeks at the end of 2002 and beginning of this year with "Lose Yourself."
