Chart Beat: Katy Perry, Kathy Griffin, Miley Cyrus

Fred discusses the 1000th No. 1 of the rock era, Kathy Griffin's comedy album, Miley Cyrus and more!

ROCKIN' AND KISSIN': Music historians acknowledge that the rock era was ushered in by one 45 rpm single: "(We're Gonna) Rock Around the Clock" by Bill Haley & His Comets, the first rock and roll song to go to No. 1 on the Billboard pop chart. The importance of that record moving into the top slot wasn't obvious when it happened 53 years ago this week, but the single that advances to No. 1 this week makes a much more obvious accomplishment. Katy Perry's "I Kissed a Girl" (Capitol) is the 1000th No. 1 of the rock era.

Chart Beat readers have been writing me for months, speculating which artist would claim the honor of having the 1000th No. 1. Some thought it would be Mariah Carey with a track from her "E=MC2" set, or the winner of the seventh season of "American Idol" or a new single from Madonna's "Hard Candy." Instead, the 1000th No. 1 belongs to a relatively new artist with her first Hot 100 chart entry, a song that caught on quickly and sped up the chart, reaching the summit in its seventh week.

Since we've arrived at the 1000th No. 1 single of the rock era, it's a good time to look back and see which songs helped get us here, starting with the 100th No. 1:

100: "Big Bad John," Jimmy Dean (Nov. 6, 1961)
200: "Paint It Black," The Rolling Stones (June 11, 1966)
300: "Maggie May" / "Reason to Believe," Rod Stewart (Oct. 2, 1971)
400: "Lovin' You," Minnie Riperton (April 5, 1975)
500: "What a Fool Believes," Doobie Brothers (April 14, 1979)
600: "Like a Virgin," Madonna (Dec. 22, 1984)
700: "Together Forever," Rick Astley (June 18, 1988)
800: "Set Adrift on Memory Bliss," P.M. Dawn (Nov. 30, 1991)
900: "It's Gonna Be Me," 'N Sync (July 29, 2000)

I should point out that "I Kissed a Girl" is the 1000th No. 1 of the rock era, not the 1000th No. 1 on the Hot 100. The chart as we know it today was first published Aug. 4, 1958, three years and one month after the rock era began. Before the Hot 100, the official singles chart of the day was Best Sellers in Stores. The first 39 No. 1 songs of the rock era topped the Best Sellers tally. The song that was No. 1 on the first Hot 100 was "Poor Little Fool" by Ricky Nelson. "I Kissed a Girl" is thus the 961st No. 1 on the Hot 100.

There are other notable facts about this new chart-topping title besides being the 1000th No. 1. Perry's single is the 53rd No. 1 of the rock era for the Capitol label. With "I Kissed a Girl" replacing Coldplay's "Viva La Vida" at the apex, this is the first time in 32 years that Capitol has had back-to-back No. 1 hits. In May 1976, the Sylvers' "Boogie Fever" was succeeded by Paul McCartney's "Silly Love Songs."

FUNNY GIRL: Emmy-winner Kathy Griffin claims the prime reason she has released a comedy album is to win a Grammy. But was she also aiming for having the highest-charting title by a female comedian in the last 25 years?

Maybe Grammy voters will take notice of Griffin's chart feat and hand her the statuette she covets. "For Your Consideration" (Music With a Twist) enters The Billboard 200 at No. 85. That's the highest-ranked album by a female comedian since 1983, when Joan Rivers cracked her way to No. 22 with, "What Becomes a Semi-Legend Most?"

Charted albums by female comedians are rare, but there have been at least three in the last four decades that have charted higher than Griffin's. In 1971, Lily Tomlin's debut LP, "This Is a Recording," raced to No. 15. The follow-up, "And That's the Truth," climbed to No. 41 a year later. In 1980, Gilda Radner's "Live from New York" reached No. 69.

On Top Comedy Albums, Griffin's "Consideration" bows at No. 1, the first album by a woman to lead this list. Since the chart was initiated in 2004, only males and soundtracks have been on top. Here is a summary of the men who have visited the comedic penthouse, and for how long:

69 weeks: Dane Cook
43 weeks: Larry the Cable Guy
22 weeks: "Weird Al" Yankovic
19 weeks: Flight of the Conchords
9 weeks: Ron White
6 weeks: Bill Engvall
1 week: Jeff Foxworthy
1 week: Eddie Izzard
1 week: Patton Oswalt
1 week: Nick Swardson

CYRUSES THREE: Miley Cyrus' new single, "7 Things" (Hollywood), surges 70-10 on the Hot 100, tying the peak position of "See You Again" just two months ago. These two singles are Cyrus' biggest hits on the chart and her only top 10 hits.

Miley's father, Billy Ray Cyrus, had his first top 10 hit 16 years ago, when "Achy Breaky Heart" went to No. 4 in July 1992.

Last week, Trace Cyrus (stepson of Billy Ray and half-sister to Miley) became the third member of his family to have a top 10 hit on the Hot 100 when his group, Metro Station, moved up to No. 10 with "Shake It" (Red Ink). That single falls to No. 13 this week.

HIGH 'CAMP': Miley Cyrus' pal Joe Jonas helps set a new record on the Hot 100, where four singles from one soundtrack debut inside the top 40. Leading the way for the "Camp Rock" quartet is "This Is Me" by Demi Lovato and Joe Jonas, new at No. 11. Also debuting: "Play My Music" by the Jonas Brothers (No. 20), "Gotta Find You" by Joe Jonas (No. 30) and "We Rock" by the Cast of "Camp Rock" (No. 33).

18 WITH A BULLET: Rihanna has had three No. 1 hits to date on the Hot 100, but she's never had a song debut in the top half of the chart, until now.

"Disturbia" (SRP/Def Jam), one of the new tracks added to an extended version of "Good Girl Gone Bad," is a new entry at No. 18. That's miles ahead of her previous highest debut, "Unfaithful," which opened at No. 51 in May 2006.

'FEET' FEAT: For the first time since 1999, Donna Summer has two consecutive No. 1 hits on Hot Dance Club Play. "Stamp Your Feet" (Burgundy) follows "I'm a Fire," which was the hottest song on the chart dated April 19. To find two Summer No. 1s in a row before this year's pair, one would have to go back nine years, when "I Will Go With You (Con Te Partiro)" and "Love Is the Healer" were both No. 1.

"Stamp Your Feet" is the 12th Donna Summer song to head up the Club Play survey.
