For the ninth week in a row, Mario's single "Let Me Love You" sits atop Billboard's Hot 100. This year's Valentine's Day anthem is also No. 1 on Billboard's Hot R&B/Hip-Hop Singles & Tracks and Hot 100 Airplay charts for the same number of weeks.

But on the Hot 100, Mario is starting to see the first sign of real competition as 50 Cent's "Candy Shop" featuring Olivia makes a rapid 8-2 ascent this week. The chart's greatest gainer at radio is one of 50 Cent's three current top 10 titles. It also logs a second week at No. 1 on the Hot Digital Songs tally.

Green Day's "Boulevard of Broken Dreams" spends a second week at No. 3 on the Hot 100, and tops the Pop 100 for a second week, the Mainstream Rock Tracks for an eighth, the Modern Rock Tracks for a 12th and advances 2-1 on the Adult Top 40 list.

As reported yesterday, the Grammy winner for best rock album saw a 20% U.S. sales increase to 135,500 copies of "American Idiot" (Reprise), according to Nielsen SoundScan, which is No. 3 on The Billboard 200.

Though a seven-week stint at No. 2 on the Hot 100 ends with a fall to No. 4, Ciara's "1, 2 Step" featuring Missy Elliott sees gains on other Billboard charts. In addition to notching a second week at the summit of the Pop 100 Airplay chart, the track moves 2-1 to take over the lead on the Hot Dance Radio Airplay list.

The Game's "How We Do" featuring 50 Cent drops 4-5, while 50 Cent also drops one slot to No. 6 with "Disco Inferno." "Hate It or Love It," another the Game track featuring 50 cent, sees a significant gain, however, rising 81-58.

Lil Jon & the East Side Boyz's "Lovers and Friends" featuring Usher and Ludacris also falls one spot to No. 7, but remains at No. 1 on Billboard's Hot Rap Tracks list for a seventh week. In addition, the cut jumps to No. 1 on the Hot R&B/Hip-Hop Airplay chart and the Rhythmic Airplay tally.

Destiny's Child's "Soldier" featuring T.I. & Lil Wayne slides 7-8 on the Hot 100, while Kelly Clarkson's "Since U Been Gone" remains No. 9 for a third week.

Gwen Stefani's "Rich Girl" featuring Eve is the Hot 100's fastest-growing digital song, and rockets 16-10 to round out the top tier. The duo performed the song during the Feb. 13 Grammy Award ceremony. Stefani's "What You Waiting For?" also re-enters the chart at No. 91.

The Postal Service's "We Will Become Silhouettes" is the Hot 100's top debut at No. 82 and marks the first appearance on the chart for the electronica-enhanced rock act. The song is the latest single from 2003's "Give Up" (Sub Pop), which spent one week atop Billboard's Top Heatseekers chart and has sold 507,000 copies since its February 2003 release.

Also debuting this week are Akon's "Lonely" (No. 90), Toby Keith's "Honky Tonk U" (No. 93), Ying Yang Twins' "Wait (The Whisper Song)" (No. 94), the Caesars' "Jerk It Out" (No. 95), Baby Bash's "Baby I'm Back" featuring Akon (No. 97) and Joe Nichols' "What's a Guy Gotta Do" (No. 100).
