Billboard Hot 100, 7/5/2008

1. I Kissed a Girl - Katy Perry

Fifty-three years in, the rock era offers up its 1000th #1 hit, as Katy Perry ascends to the top spot with her first major hit, "I Kissed a Girl." If one of rock's central tenets is pushing buttons, then "I Kissed a Girl" is an apt choice for this honor: the song involves a girl kissing another girl for the first time.

5. Pocketful of Sunshine - Natasha Bedingfield

Natasha Bedingfield's "Pocketful of Sunshine" reaches its highest peak so far at #5, tying the peak position of "Unwritten," her highest-charting single so far.

9. When I Grow Up - The Pussycat Dolls

The Pussycat Dolls scores their 4th top 10 hit this week with "When I Grow Up," which climbs 9 spots to #9. This is their fastest rise into the top 10, as the single is only in its fourth week on the Hot 100.

10. 7 Things - Miley Cyrus

Here's this week's biggest mover. Miley Cyrus climbs 60 spots to score her third top 40 and second top 10 hit with "7 Things." Her last single, "See You Again," was on the chart for quite awhile, but only ever made it to #10. "7 Things" may slide a bit, as this massive leap is owed to the single finally being available this week at iTunes, but since it continues to rise in airplay, could ultimately be a bigger hit. This is the first single from Cyrus's forthcoming second studio album, Breakout.

11. This Is Me - Demi Lovato & Joe Jonas
20. Play My Music - Jonas Brothers
30. Gotta Find You - Joe Jonas
33. We Rock - Cast of Camp Rock

The latest Disney musical, "Camp Rock," is responsible for four new entries in this week's top 40. All feature Joe Jonas, a member of the Disney darlings band the Jonas Brothers, who get their second top 40 hit with "Play the Music." The brothers also have a new entry at top 40 radio, "Burnin' Up," from their forthcoming third album.

18. Disturbia - Rihanna

Sadly, it looks like Rihanna's Maroon 5 collaboration, "If I Never See Your Face Again," is going to miss the top 40, but she quickly makes up for that failure with this new single "Disturbia," which debuts at #18. She's also at #4 with "Take a Bow," her third current single. "Disturbia" is Rihanna's 11th top 40 hit.

50. Apologize - Timbaland Featuring OneRepublic

This looks like the last week on the chart for Timbaland and OneRepublic's massive hit "Apologize," which has now spent 47 weeks on the Hot 100. Not a record, but quite impressive.
