Khalifa also bounds in at No. 1 on the Top R&B/Hip-Hop Albums chart and the Rap Albums chart.



Last week's No. 1, the Guardians of the Galaxy soundtrack, falls to No. 2 with 64,000 (down 30 percent).

The album's current single, "Ready Set Roll," spends a second week at No. 12 (its peak) on the Hot Country Airplay chart. The album was released through Dack Janiels Records and distributed through Red Distribution (Sony Music's independent distribution arm).



Rice first gained fame as a contestant on the CBS TV series "Survivor: Nicaragua" in 2010. He later co-wrote Florida Georgia Line's massive single "Cruise" (No. 1 for a record 24 weeks on Hot Country Songs).



Back on the new Billboard 200, the Now 51 compilation dips 2-4 with 33,000 (down 36 percent).



The star-studded country compilation Nashville Outlaws: A Tribute to Motley Crue kickstarts at No. 5 with 31,000 and also drives in at No. 2 on Top Country Albums. Released on Big Machine Records, the set includes reworkings of Motley Crue tunes by acts like Rascal Flatts ("Kickstart My Heart"), Brantley Gilbert ("Girls, Girls, Girls") and Justin Moore ("Home Sweet Home," featuring Motley Crue's Vince Neil).



The Frozen soundtrack slides 3-6 with 29,000 (down 33 percent), Sam Smith's In the Lonely Hour holds at No. 7 with a little more than 24,000 (down 6 percent), and 5 Seconds of Summer's self-titled set decends 6-8 with 24,000 (down 12 percent).



Former Kiss guitarist Ace Frehley nets his highest-charting album (and first top 10), as Space Invader debuts at No. 9 with 19,000 sold. It surpasses the No. 26 peak of his previous highest-charting album, his self-titled 1978 debut, released at the height of Kiss mania. Space Invader is Frehley's first album since 2009's Anomaly debuted and peaked at No. 27 with a 17,000 sales start.



Ed Sheeran's x rounds out the top 10, returning to the region (12-10) with 16,000 (down 12 percent).

Over on the Digital Songs chart, Taylor Swift's "Shake It Off" blasts in at No. 1, selling 544,000 downloads in its first week — the biggest sales week of 2014 and the fourth-largest debut week ever.



The only starts that were larger were logged by Flo Rida's "Right Round" (636,000 in 2009), Swift's "We Are Never Ever Getting Back Together" (623,000 in 2012) and Katy Perry's "Roar" (557,000 in 2013).

"Shake It Off" is the first single from Swift's upcoming fifth studio album, 1989, which is due to be released Oct. 27. The song was released commercially on Monday, Aug. 18.



Last week's Digital Songs No. 1, Meghan Trainor's "All About That Bass," falls to No. 2, despite a sales gain. It sold 283,000 downloads (up 18 percent).



Jessie J, Ariana Grande and Nicki Minaj's "Bang Bang" is also pushed back even though it makes a gain, as the diva team-up slips 2-3 with 159,000 (up 21 percent). Like many of the songs in the top 10, this track benefits from a performance on the 2014 MTV Video Music Awards, which were broadcast Aug. 24, the final day of the latest sales tracking week. "Bang Bang" was one of the three songs that opened the awards show, as Grande also performed her own "Break Free" and Minaj did her single "Anaconda." The latter track slithers 24-6 with 120,000 (up 132 percent) following the double-whammy of the VMAs performance and the Aug. 20 premiere of its music video.

Iggy Azalea's "Black Widow," featuring Rita Ora, moves 3-4 with 142,000 (up 14 percent), and Smith's "Stay With Me" holds at No. 5 with 122,000. Both were also performed on the VMAs.



Clean Bandit's "Rather Be," featuring Jess Glynne, climbs 8-7 with 104,000 (up 9 percent). Charli XCX's "Boom Clap" steps 12-8 with 97,000 (up 22 percent) after it was performed on the VMA’s pre-show. Sia's "Chandelier," which was nominated for a number of VMAs -— including video of the year — rises 10-9 with 96,000 (up 3 percent). It wasn’t performed on the show, but did take home a non-televised category: best choreography.



Magic's "Rude" closes out the top 10, descending 7-10 with 88,000 (down 15 percent).



Overall album sales in this past chart week (ending Aug. 24) totaled 3.97 million units, down 3 percent compared with the sum last week (4.11 million) and down 19 percent compared with the comparable sales week of 2013 (4.9 million). Year-to-date album sales stand at 154.5 million, down 15 percent compared with the same total at this point last year (181 million).



This week's 3.97 million total is the smallest weekly sum for album sales since SoundScan began tracking data in 1991. It's also the first time weekly sales have fallen below 4 million in that time span.



Digital track sales this past week totaled 19.2 million downloads, down 2 percent compared with last week (19.6 million) and down 13 percent stacked next to the comparable week of 2013 (22.1 million). Year-to-date track sales are at 754.4 million, down 13 percent compared with the same total at this point last year (865.4 million).



Next week's Billboard 200 competes with the same week in 2013 when: Avenged Sevenfold's Hail to the King debuted at No. 1 with 159,000, while the previous week's leader, Luke Bryan's Crash My Party, fell to No. 2 with 92,000 (down 42 percent).
