Nelly Furtado's "Say It Right" ends the 10-week reign of Beyonce's "Irreplaceable" at No. 1 on the Hot 100 with a 2-1 climb. It's Furtado's second No. 1 from her album "Loose," following "Promiscuous," which reached the top six months ago. "Irreplaceable" slides to No. 2, ending the longest run at the top since Kanye West's "Gold Digger" featuring Jamie Foxx also spent 10 weeks there last year.

Elsewhere on the Hot 100, Gwen Stefani's "The Sweet Escape" featuring Akon rises 5-3 for a new peak, while Fall Out Boy's "This Ain't a Scene, It's An Arms Race" is down 3-4.

Gym Class Heroes' "Cupid's Chokehold" featuring Patrick Stump zooms 15-7, giving the group its first top 10 hit. Justin Timberlake's "What Goes Around ... Comes Around" rises 11-8, while Fergie's "Glamorous" featuring Ludacris rockets 31-9 as the chart's top digital gainer. Fergie thus earns her third top 10 solo hit in six months, equal to her group the Black Eyed Peas' tally over the past six years.

Akon's "I Wanna Love You" featuring Snoop Dogg rounds out the top 10, falling 7-10. But he's got another track poised for top 10 success in the form of "Don't Matter," which climbs 30-11 this week. Meanwhile, rapper Mims' "This Is Why I'm Hot" is the chart's fastest growing track at radio for a second week in a row and jumps 59-46, while Jordan Pruitt has the week's top debut with "Outside Looking In" at No. 77.

Also new this week is Sheryl Crow's cover of Buddy Holly's "Not Fade Away" at No. 78, Timbaland's "Give It To Me" featuring Furtado and Timberlake at No. 87, Yung Joc's "1st Time" featuring Marques Houston and Trey Songz at No. 93, UNK's "2 Step" at No. 94 and Crime Mob's "Rock Yo Hips" featuring Lil Scrappy at No. 100.

On Hot R&B/Hip-Hop Songs, Robin Thicke's "Lost Without U" flip-flops 2-1 with Lloyd's "You" featuring Lil' Wayne. He joins Alicia Keys and Blige as the only artists since 2000 to top this chart and the Adult R&B tally with the same single while also leading the Top R&B Albums chart in the same week.

George Strait earns his 42nd No. 1 on Billboard's Hot Country Songs chart with "It All Comes Natural," ending Rodney Atkins' four-week reign at the top. Big & Rich's "Lost in This Moment" is the chart's top debut at No. 41, the best opening of the unconventional duo's career. Its next album, "Between Raising Hell and Amazing Grace," is due June 5.

Luis Fonsi climbs 11-1 to overtake the Hot Latin Songs chart, which had been ruled by Hector El Father's "Sola" for three weeks. John Mayer earns his first No. 1 on the Adult Contemporary chart with "Waiting on the World To Change," bumping 10-week chart-topper "Unwritten" by Natasha Bedingfield back down to No. 2.
