After setting a chart record with a 64-1 jump last week, Maroon 5's "Makes Me Wonder" remains No. 1 for a second stanza on the Billboard Hot 100. But it has strong competition in the form of Ne-Yo's "Because of You," which climbs 5-2 and is the chart's fastest growing digital track, and T-Pain's "Buy U a Drank (Shawty Snappin')," which rises 4-3 and is the fastest growing track at radio for a sixth week.

Avril Lavigne's "Girlfriend" is down 2-4 this week, while Timbaland's "Give It to Me" featuring Nelly Furtado and Justin Timberlake falls 3-5. Carrie Underwood's "I'll Stand by You" holds at No. 6, as does Fergie's "Glamorous" featuring Ludacris at No. 7. Akon's "Don't Matter" inches up 9-8, and the artist also occupies the next two slots as a guest, first on Bone Thugs-N-Harmony's "I Tried," which climbs 11-9, and on Gwen Stefani's "The Sweet Escape," which holds at No. 10.

Bon Jovi's "(You Want To) Make a Memory" is the chart's top debut at No. 27, the highest opening of its long career. The track sold 51,000 digital downloads following the band's recent performance of it on "American Idol."

Also new this week is Green Day's cover of John Lennon's "Working Class Hero" at No. 53, Freak Nasty's "Do It Just Like a Rockstar" featuring Crazy Mike at No. 77 and Down AKA Kilo's "Lean Like a Cholo" at No. 93.

"Buy U a Drank" is No. 1 for a second week on Hot R&B/Hip-Hop Songs, on which R. Kelly and Usher score the chart's best debut since 2004 with "Same Girl." The track, which will be found on Kelly's upcoming Jive album, "Double Up," opens at No. 16. The new album's first single, "I'm a Flirt," recently peaked at No. 2 and is No. 3 this week.

On Hot Country Songs, Sugarland's "Settlin'" flip-flops with Rascal Flatts' "Stand" to take over at No. 1. Fro the first time since Billboard converted this list's rankings from total plays to audience impressions in January 2005, the top two titles finish the tracking week in a statistical tie with 35.1 million impressions. The longstanding tie-breaker rule is the amount of gain or loss for each title: Sugarland's grows by 224,000 impressions while Rascal Flatts' declines by 1.9 million.

Enrique Iglesias' "Dimelo" explodes 49-1 on Hot Latin Songs in just its second week, his 17th No. 1 hit on the tally. The artist's new Interscope album, "Insomniac," arrives June 12.

Linkin Park continues to dominate the Modern and Mainstream Rock charts with "What I've Done," beginning a fifth week atop the former and a second on the latter.
