Also, Meghan Trainor's "All About That Bass" hits No. 1 on the Digital Songs chart.

The Guardians of the Galaxy soundtrack rises to No. 1 on the Billboard 200, becoming the second chart-topping soundtrack of 2014.

The blockbuster film's set, subtitled Awesome Mix Vol. 1, sold 109,000 copies in the week ending Aug. 10 (up 83 percent), according to Nielsen SoundScan. It debuted a week ago at No. 3 with 60,000.

The 12-song multi-artist collection follows Frozen as the second soundtrack to top the chartthis year. Both albums were released by the Disney Music Group. (The company's Hollywood Records issued Guardians of the Galaxy while Walt Disney Records released Frozen.)

2014 is the first year since 2009 where multiple theatrical film soundtracks reached No. 1. Three movie sets topped the list in 2009: Hannah Montana: The Movie, The Twilight Saga: New Moon and Michael Jackson's This Is It

Why a '70s Mixtape Propels the Plot of 'Guardians of the Galaxy'

Guardians of the Galaxy is an especially notable No. 1 album because it is the first No. 1 soundtrack where the whole album is composed of previously released songs. All of its tunes were released between the late 1960s and late 1970s, and most were chart hits on the Billboard Hot 100.

The album and its music play an important role in the movie: They are all on a mixtape in the main character's Walkman, which was given to him by his late mother. (All but one of the soundtrack album's dozen songs are heard in the film, too.)

As for the rest of the top 10, the Now 51 compilation enters at No. 2 with 94,000, giving the long-running Now That's What I Call Music! franchise its 57th top 10 album. All 51 of the titles in the main series have hit the top 10, while an additional six Now-branded titles (like Now That's What I Call Christmas! ) have reached the top 10.

Godsmack starts at No. 3 with its newest album, 1000HP, selling 58,000. It's the band’s first full-length studio album to not enter at No. 1 since 2000's Awake debuted and peaked at No. 5. Following that project, the act notched three straight chart-toppers with the studio efforts Faceless (2003), IV (2006) and The Oracle (2010). The band also nabbed a top 10 EP in that span of time with The Other Side (No. 5) in 2004.

Another rock band, Spoon, rounds out the new arrivals in the top four, as its latest, They Want My Soul, bows at No. 4 with 39,000. It's the third top 10 for the group, which previously visited the region with 2010's Transference (No. 4) and 2007's Ga Ga Ga Ga Ga (No. 10).

Tom Petty Scores First No. 1 Album On Billboard 200

Last week's No. 1 album, Tom Petty and The Heartbreakers' Hypnotic Eye, falls to No. 6 in its second week with 34,000 (down 74 percent). It's right behind 5 Seconds of Summer's self-titled set, which falls 4-5 with 36,000 (down 35 percent). Eric Clapton & Friends' all-star tribute album, The Breeze: An Appreciation of JJ Cale, descends 2-7 with 29,000 (down 52 percent). The Frozen soundtrack shifts 6-8 (28,000, down 15 percent), and Sam Smith's In the Lonely Hour moves 7-9 (27,000, down 10 percent).

New U.K. pop band The Vamps arrive at No. 10 with debut EP Somebody to You. The quartet's effort sells 20,000 and is the fifth EP to debut in the top 10 this year. A year ago at this point, no EPs had arrived in the top 10. Just last week Shawn Mendes' self-titled EP arrived at No. 5. It falls to No. 32 in its second week.

Over on the Digital Songs chart, a new No. 1 is crowned, as Meghan Trainor's "All About That Bass" rises 2-1 with 197,000 downloads sold (up 17 percent).

Jessie J, Ariana Grande and Nicki Minaj's "Bang Bang" drops 1-2 in its second week, selling 141,000 (down 39 percent).

Minaj makes a second appearance in the top three, as her new solo single, "Anaconda," bows at No. 3 with 141,000. She is the first lead act to have two concurrent songs in the top three of the chart since the Sept. 22, 2012 list. That week, Taylor Swift led with "We Are Never Ever Getting Back Together" at No. 1 and "Ronan" at No. 2.

Smith's "Stay With Me" remains at No. 4 on the new Digital Songs chart with 123,000 (down 11 percent), Magic's "Rude" is also steady at No. 5 with 122,000 (down 8 percent), and Jason Aldean's "Burnin' It Down" is another stationary track, sitting at No. 6 for another week (107,000; down 7 percent).

Iggy Azalea's "Black Widow," featuring Rita Ora, climbs 8-7 with 106,000 (up 6 percent), and Azalea's "Fancy," featuring Charli XCX, slips 7-8 with 98,000 (down 8 percent). Maroon 5's "Maps" tumbles 3-9 with 97,000 (down 31 percent), and Sia's "Chandelier" moves 9-10 with 91,000 (down 7 percent).

Overall album sales in this past chart week (ending Aug. 10) totaled 4.27 million units, down 1 percent compared with the sum last week (4.33 million) and down 9 percent compared with the comparable sales week of 2013 (4.7 million). Year-to-date album sales stand at 146.4 million, down 14 percent compared with the same total at this point last year (171 million).

Digital track sales this past week totaled 20.2 million downloads, down 1 percent compared with last week (20.4 million) and down 8 percent stacked next to the comparable week of 2013 (22.1 million). Year-to-date track sales are at 715.6 million, down 13 percent compared with the same total at this point last year (820.2 million).

Next week's Billboard 200 competes with the same week in 2013 when: Luke Bryan's Crash My Party debuted at No. 1, selling 528,000 in its first week. K. Michelle's Rebellious Soul arrived in the runner-up spot, selling 72,000.
