As previously reported, Carly Rae Jepsen holds on for an eighth straight week at No. 1 on the Billboard Hot 100, tying Gotye's "Somebody That I Used to Know" for the longest run at the top this year. Katy Perry's "Wide Awake" jumped to No. 2 and Flo Rida's "Whistle" blew into the top five. But of course, there was more action even farther down the chart -- let's take a gander:

-- Justin Bieber: The singer's "As Long As You Love Me" surges 46-14 on Hot Digital Songs and 22-9 on Pop Digital Songs (78,000 downloads sold, up 87%). In turn, it rises 53-28 on the Billboard Hot 100, 60-48 on Hot 100 Airplay (25 million, up 31%) and re-enters On-Demand Songs at No. 36 (287,000, up 23%).

Carly Rae Jepsen's 'Call Me Maybe' Ties Gotye for Most Weeks at No. 1 This Year

It's heading back up the Hot 100 after it made a splashy debut six weeks ago at No. 21. Its bow that week was fueled by its release as an early preview track from the album via iTunes. In the ensuing weeks, it moved to 87, then 82-66-53 and now up to No. 28.

The track is the second radio single from Bieber's "Believe" album, which spawned the No. 2 Hot 100 hit "Boyfriend." So far, the young superstar has notched 28 hits on the Hot 100, with three of those reaching the top 10.

-- Kelly Clarkson: As her "Dark Side" song (54-49 on the Hot 100) jumps 12-9 on the Adult Top 40 chart, she breaks a three-way tie for the most top 10s (11) among women in the airplay list's 16-year history, passing Sheryl Crow and Katy Perry. Clarkson has earned a total of 17 hits on the chart, with four of those going all the way to No. 1: "Behind These Hazel Eyes (five weeks at No. 1), "Already Gone" (eight weeks), "Mr. Know It All" (six weeks) and "Stronger (What Doesn't Kill You)" (eight weeks).

-- No Doubt: Though its single "Settle Down" drops this week on the Hot 100 (falling 34-57), it's rising fast on our airplay charts. It jumps 23-17 on the Adult Top 40 tally, 22-19 on Rock Songs and 35-25 on Mainstream Top 40. After its initial splash on the Hot 100 (thanks to out-of-the-gate download sales), the track plummets 13-63 on Digital Songs (32,000; down 63%).

-- Nicki Minaj: Her latest single "Pound the Alarm" arrives at No. 92 and clocks at 39-31 advance on Mainstream Top 40. It also bows as the highest new entry on the Hot 100 Airplay chart at No. 66 (18 million audience impressions, up 92%). "Pound the Alarm" is Minaj's 41st Hot 100 single in a chart career than only began on Feb. 20, 2010.

-- Train: The band's single "Drive By" (26-29 on the Hot 100) chugs to No. 1 on the Adult Contemporary chart, marking the group's third lead on the tally. The act first reigned on the AC chart for three weeks in 2004 with "Calling All Angels" and returned for a 22-week command with "Hey, Soul Sister" in 2010-11. (That's the chart's second-longest No. 1-run after Uncle Kracker's "Drift Away," featuring Dobie Gray [28 weeks, 2003-04].)
