A quick look at the most notable jumps and drops on this week's Billboard 200 albums and Hot 100 singles charts.

The Billboard 200:

-- Arcade Fire: The Canadian band made waves atop the Billboard 200 albums chart this week as its "The Suburbs" entered the tally at No. 1 with 156,000, giving the act its first chart-topper. And that Merge album was just one of four debuts in the top 10 this week. But, let's see what else is cooking on the Billboard 200 -- and the Billboard Hot 100 singles chart -- this week.

-- Train: After the band performed on NBC's "Today" on Aug. 6, their album "Save Me, San Francisco" motors with a 27% gain and its best sales week (14,000) since May. It moves up the chart 11 slots to No. 20.

-- Step Up 3D: Naturally, since the film opened in theaters during the tracking week, its companion soundtrack sees an increase (rising 44 spots to No. 36; up 78% in sales). However, it has a ways to go before reaching the peaks of the first two albums in the dance movie series, which topped out at Nos. 6 and 5, respectively.

-- MercyMe: With "The Generous Mr. Lovewell" album's first gain since late June, the set likely benefits from back-to-school promotions at Family Christian and Lifeway retailers. The album is up 27% to a weekly total of 4,000 -- rising 44 places to No. 112.

-- Janelle Monae: Her album "The ArchAndroid: Suites II And II" strikes with a 55-slot leap to No. 120 (the biggest positional gain on the chart) thanks to publicity generated from her performance on the Aug. 5 edition of Fox's "So You Think You Can Dance?" The set's sales gain is 27% -- the largest percentage jump on the chart.

-- LCD Soundsystem: Amazon MP3 store's month-long promotion of $5 alternative and rock albums perhaps aids the act's "Sound of Silver" album (rising 185-136 -- up 26% overall and 44% in downloads) and Mumford & Sons' "Sigh No More" at Nos. 26 (climbing nine slots -- up 12% overall; 26% in downloads).

-- Dru Hill: A pair of albums from Dru Hill (No. 151 with "InDRUpendence Day") and Best Coast (No. 137 with "Crazy For You") fall more than 100 positions in their second week on the chart. Dru Hill entered the list last week at No. 30 with 11,000 but slides 69% this week: a drastic (but not surprising) drop for the reunited group, which hasn't been on any singles chart since April. As for Best Coast (down 63% from No. 36 last week), its start with 10,000 was pumped due to promotion from its "Boyfriend" track's selection as iTunes' free Discovery Download. Now that it's no longer getting front page love in the iTunes Store, the set slides.

The Billboard Hot 100

-- Taylor Swift: Taylor Swift becomes the second female in the history of the Hot 100 to debut multiple tracks in the top five during a calendar year as "Mine" enters at No. 3, falling one spot shy of the debut and peak of "Today Was a Fairytale" from February. Mariah Carey is the only other female with multiple top five debuts in a single year, opening at No. 1 with both "Fantasy" and "One Sweet Day," with Boyz II Men, in 1995. "Mine," the first single from Swift's forthcoming album "Speak Now," opens at No. 1 on Hot Digital Songs with 297,000 downloads in a partial sales week, according to Nielsen SoundScan, as it was released on Wednesday, August 4, two-and-a-half days into the tracking period. On the airplay side, "Mine" starts at No. 53 on Radio Songs with 23.9 million listener impressions, according to Nielsen BDS, with roughly 60% of that audience coming from country radio and the rest from top 40 and adult outlets. On the Country Songs tally, "Mine" starts its chart life at a lofty No. 26.

-- Eminem: He holds at No. 1 for a fourth week on the Hot 100 with "Love they Way You Lie," featuring Rihanna. While the song is displaced from the top slot on Hot Digital Songs by Swift's arrival, it moves 2-1 on Hot 100 Airplay with 144.2 million listener impressions, giving the rapper his second No. 1 on that list. He previously led with "Lose Yourself" for 11 weeks from November 2002 to January 2003.

-- Taio Cruz: He moves into the runner-up spot on the Hot 100 with Airplay Gainer honors for "Dynamite" as audience impressions increase to 103.1 million, according to Nielsen BDS, (up 22%). The title is still a good distance from Eminem's chart leader, trailing "Lie" by roughly 70,000 downloads and 40 million listener impressions.

-- B.o.B: "Magic," the rapper's collaboration with Weezer's lead man Rivers Cuomo, is the Hot 100 Digital Gainer, jumping 22-15 on the big list and 14-11 on Hot Digital Songs. Though it's only a three-spot jump on the latter chart, it represents a 32,000 unit gain (up 46%) to bring weekly downloads into the six-digit range (100,000).

-- Kenny Chesney: He makes a huge leap on the Hot 100, rising 96-18 with "The Boys of Fall" as first-week downloads (82,000) drive the song's upward surge (No. 14 debut on Digital Songs). Chesney betters his own record for largest opening-week downloads by a male country artist previously set with "Out Last Night" (71,000) in June 2009. "Out Last Night" still stands as his best Hot 100 showing, having peaked at No. 16.

-- Linkin Park: Multi-platinum band makes a strong entry onto the Hot 100 at No. 35 with "The Catalyst." In addition to its fast start at radio, where it debuts at No. 1 on Rock Songs, the track opens with 60,000 downloads, placing it at No. 20 on Hot Digital Songs and No. 1 on Rock Digital Songs.

-- OneRepublic: The band might not need to apologize for its latest effort "Secrets," which peaked at No. 35 two weeks ago, but it has so far fallen well short of "All the Right Moves," the leadoff track from their sophomore set "Waking Up," which topped out at No. 18 in April. Since "Apologize" reached No. 2 in November 2007, the act has not been able to reach the top 10 with its five subsequent entries. "Secrets" posts a second straight week of download decline (-19%), but with radio play increasing-- it reaches a new high on the Adult Top 40 radio chart (34-23) and holds at No. 30 on Mainstream Top 40 with a gain in plays-the song has a chance to rebound on the sales tally as well as the Hot 100.

-- The Script: After the breakthrough of "Breakeven," (it falls to No. 21 this week), Epic Records decided to re-work "The Man Who Can't Be Moved," the first single from the band's debut album, to radio. In its first go-round it reached No. 15 on the Adult Top 40 chart in June 2009. Its appearance on the Mainstream Top 40 chart (No. 34) has spurred digital sales (15,000, up 42%), helping to bring it onto the list at No. 96.
