The Black Eyed Peas extended their unprecedented run at the top of Billboard's Hot 100 singles chart to 21 weeks on Thursday, while Miley Cyrus kept partying at No. 2.

The hip-hop group led the field with I Gotta Feeling, whose eight-week reign directly followed a 13-week run by Boom Boom Pow, both tracks from its chart-topping album The E.N.D. The one-two punch last week broke Usher's record from 2004, when Yeah! and Burn were No. 1 for a total of 19 consecutive weeks.

Cyrus' Party In the U.S.A. followed at No. 2, a week after debuting at that spot. The track comes from Cyrus' Walmart exclusive CD The Time of our Lives, due August 31.

Down, by Jay Sean featuring Lil Wayne, jumped four places to No. 3, Taylor Swift's You Belong With Me held at No. 4, while Jay-Z, Rihanna and Kanye West's Run This Town fell two to No. 5.

Kings of Leon's Use Somebody (No. 6) and Drake's Best I Ever Had (No. 7) were each down one place. The rest of the top-10 was unchanged: Keri Hilson featuring Kanye West and Ne-Yo's Knock You Down at No. 8, Cobra Starship featuring Leighton Meester's Good Girls Go Bad at No. 9, and Pitbull's Hotel Room Service at No. 10.

The top debut was Kenny Chesney and Dave Matthews' I'm Alive, at No. 90. It's the third charting single from Chesney's chart-topping Lucky Old Sun.

In other chart news, Jason Aldean roped his third No. 1 on Billboard's Hot Country Songs tally as Big Green Tractor jumps two places to No. 1. The rise gives Aldean back-to-back toppers, following She's Country, which spent one week at No. 1 on May 16.
