Jepsen makes Canada proud by setting a Hot 100 No. 1 longevity record.

'BURN'-ING LOVE: Linkin Park logs its 11th No. 1 on Billboard's Alternative Songs radio airplay chart, as "Burn It Down" fires 3-1. The coronation pushes the group within one of Red Hot Chili Peppers for the most leaders (12) in the chart's 23-year archives.

Here's a look at the most frequent visitors to the chart's top spot:

12, Red Hot Chili Peppers

11, Linkin Park
9, Foo Fighters
9, Green Day
8, U2
6, R.E.M.
5, Bush
5, Nirvana

"Lost in the Echo" will follow "Burn" as the second single from Linkin Park's fifth studio album, "Living Things," which launched atop the Billboard 200 three weeks ago. The set has sold 349,000 copies, according to Nielsen SoundScan.

'FORMULA' FOUR SUCCESS: Romeo Santos becomes the first artist in nearly 16 years to send four cuts from a debut album to No. 1 on Latin Songs, as "La Diabla," from his debut solo set "Formula: Vol. 1," rises 5-1. The song follows "You," "Promise" and "Mi Santa" to the chart's top spot. "Formula: Vol. 1," has spent a whopping 17 weeks at No. 1 on the Latin Albums chart and all 37 of its frames on the list in the top 10.

The former Aventura member's commanding career-opening streak is the longest on Latin Songs since Enrique Iglesias arrived with eight straight No. 1s in 1995-97, the first five of which were released from his eponymous debut album.

Not bad footsteps for Santos to follow: Iglesias boasts the most No. 1s (22) in the chart's 25-year history.

HOT DIGITAL COUNTRY SONG: Here's the 411 on "5-1-5-0," Dierks Bentley's new leader on Country Songs: rising 2-1, the track is the first all-numerical No. 1 in the chart's 68-year history.

The digits 0, 1 and 5 have, however, previously occupied the summit. Zac Brown Band's "Highway 20 Ride" rolled to No. 1 in 2010; Mark Wills' "19 Somethin' " and Gary Morris' "100% Chance of Rain" ruled in 2003 and 1986, respectively; and, Dolly Parton's classic "9 to 5" worked its way to the top in 1981.

Several titles featuring numbers spelled out have graced the Country Songs summit, including many with "one" in their titles, including one by Bentley: last year's "Am I the Only One." Among others: Shania Twain's "You're Still the One" (1998) and "No One Needs to Know" (1996), LeAnn Rimes' "One Way Ticket (Because I Can)" (1996), Faith Hill's "Wild One" (1994) and Wynonna's "No One Else on Earth" (1992).

Also in numerical Country Songs news, 2011 "American Idol" runner-up Lauren Alaina's "Eighteen Inches" debuts at No. 55. The ballad, her third chart entry, was co-written by one of her idols: the series' 2005 champion, Carrie Underwood.

While Underwood has co-penned eight of her 12 Country Songs No. 1s, "Inches" marks her first chart entry recorded by another artist.
