Chart-based stories on Aerosmith, Nelly, Ashanti, Nickelback, Elvis Presley vs. JXL, Gareth Gates, and Celine Dion.

DREAM ON AND ON AND ON: It's been at least seven months since a collection of Aerosmith's greatest hits has been released, so it must be time for a new one. Voila: "O, Yeah! Ultimate Aerosmith Hits" (Columbia) enters The Billboard 200 at No. 4. That's a far superior chart position to the No. 191 peak of "Young Lust: The Aerosmith Anthology" (Geffen) in December 2001.

To be fair, that Geffen set wasn't widely publicized. The new double-CD is the first collection of the group's biggest hits to combine material from the Columbia and Geffen labels.

"O, Yeah!" is the 22nd Aerosmith album to chart in the group's 28-year, 9-month career span (dating back to the October 1973 debut of an eponymous LP). It is the band's fifth-highest charting album, bested only by "Get a Grip" (No. 1 for one week, 1993), "Nine Lives" (No. 1 for one week, 1997), "Just Push Play" (No. 2, 2001), and "Rocks" (No. 3, 1976).

AND THAT REMINDS ME: While Nelly's "Hot in Herre" (Fo' Reel/Universal) continues at No. 1 on Billboard's Hot 100 for a fourth week, there is only one former No. 1 hit from 2002 still on the chart: Ashanti's "Foolish" (Murder Inc./AJM) remains in the top-10, falling 5-9. While the other No. 1 hits from this calendar year have fallen off the Hot 100, there is still one holdover from 2001. Nickelback's "How You Remind Me" (Roadrunner) stands pat at No. 39 in its 46th chart week, making it the longest-running song on the entire Hot 100.

KING'S REIGN: The decision by RCA's U.K. office to delete "A Little Less Conversation" by Elvis vs. JXL seems likely to deny Presley a fifth week on top of the singles chart. That spoils a possible record, as "Conversation" could have been the longest-running No. 1 of the 21st century in the U.K. As it stands, "Conversation" is tied with a number of other singles that have ruled for four weeks as the longest-running chart-toppers since Cher remained in pole position for seven weeks with "Believe" in the final quarter of 1998.

The other singles that have been No. 1 for four weeks since "Believe" are:

"I Have a Dream" / "Seasons in the Sun," Westlife (1999-2000)
"Whole Again," Atomic Kitten (2001)
"Can't Get You Out of My Head," Kylie Minogue (2001)
"Hero," Enrique Iglesias (2002)
"Unchained Melody," Gareth Gates (2002)

The deletion of a single doesn't mean it disappears completely, but when retail outlets sell out of the record they can't replenish stock. That would be enough to topple "Conversation." The deletion also assures that a newly-released RCA single will debut at No. 1: the second single from "Pop Idol" runner-up Gareth Gates. "Anyone of Us (Stupid Mistake)" will be his second chart-topper, following his remake of "Unchained Melody."

'DAY' AND DATE:: "Chart Beat" has been following the progress of Celine Dion's "A New Day Has Come" (Epic) in pole position on the Adult Contemporary chart, and as the song is in its 17th week on top, it's time for an update.

"A New Day Has Come" is now tied for second place for the longest run at No. 1 on the AC chart. It is one of the five longest-running No. 1 songs in AC history. If it remains at the summit for just one more week, it will have second place all to itself. If it's still on top two weeks from now, it will be tied for first place. And three more weeks will make "A New Day Has Come" the longest-running No. 1 AC of all time.

The top five at this moment are:

"You'll Be in My Heart," Phil Collins (19 weeks, 1999
"Because You Loved Me," Celine Dion (19 weeks, 1996)
"I Knew I Loved You," Savage Garden (17 weeks, 1999)
"Breathe," Faith Hill (17 weeks, 2000)
"A New Day Has Come," Celine Dion (17 weeks to date, 2002
