Pop band 5 Seconds of Summer crashes in at No. 1 on the Billboard 200 as the Australian group's self-titled full-length debut album arrives atop the list. The set sold 259,000 copies in the week ending July 27, according to Nielsen SoundScan, following the album's release on July 22.

It's the third-largest debut of 2014, and the fourth-largest sales week. (Coldplay's Ghost Stories debuted with the year's largest week, 383,000.)

5 Seconds of Summer's opening also marks the biggest debut for an act's first full-length album this year, and the largest for a group in nearly eight years. The last group to debut with a bigger bow was Daughtry, when its self-titled debut album started with 304,000 in the week ending Nov. 19, 2006.

5 Seconds of Summer's new album follows the group's four-song introductory EP, She Looks So Perfect, which debuted and peaked at No. 2 earlier this year (selling 143,000 in its first week).

The band's homeland of Australia can also claim some amazing chart feats with the new album's debut: 5 Seconds of Summer is the first Australian act to debut at No. 1 with its first full-length album. It also logs the largest SoundScan-era sales opening for an Australian act's first album. (SoundScan began tracking data in 1991.)

5 Seconds of Summer is the second Australian act to top the Billboard 200 in 2014, following Sia, with 1000 Forms of Fear. The band is the first Australian group to hit No. 1 since AC/DC's Black Ice spent two weeks atop the tally in 2008 (on the charts dated Nov. 8 and 15).

After 5 Seconds of Summer, the long-running Frozensoundtrack rises 5-2 on the Billboard 200, selling 37,000 (down 15 percent). The album is spending its 31st consecutive week in the top five.

Last week's No. 1 album, "Weird Al" Yankovic's Mandatory Fun, falls 1-3 with 33,000 (down 68 percent). Sam Smith's In the Lonely Hour rises 6-4 with 31,000 (down 12 percent), and Kidz Bop Kids' Kidz Bop 26 slips 4-5 with 27,000 (down 42 percent).

Common's Nobody's Smiling is the chart's second-highest debut, starting at No. 5 with 24,000. It's the artist's third top 10 album, and highest-charting set since Finding Forever opened at No. 1 in 2007.

Rock band Crown the Empire is up next on the Billboard 200, entering at No. 7 with The Resistance: Rise of the Runaways (slightly more than 24,000). It's the best sales week for the Rise Records act, which previously reached the Heatseekers Albums chart with the EP The Fallout. (It did not chart on the Billboard 200.)

The Now 50 compilation is steady at No. 8 with 21,000 (down 8 percent), Jason Mraz's YES! tumbles 2-9 with 20,000 (down 75 percent), and Ed Sheeran's x descends 7-10 with slightly more than 20,000 (down 16 percent).

Over on the Digital Songs chart, Jason Aldean's "Burnin' It Down" fires up at No. 1, debuting with 184,000 downloads sold. It's Aldean's first No. 1 on Digital Songs, and his third-largest sales week (following the 189,000 debut of "Take a Little Ride" in 2012 and a 189,000 frame for "Dirt Road Anthem" in 2011).

The new single previews Aldean's upcoming studio album, which will arrive before the end of the year.

Aldean bumps Magic's "Rude" from the No. 1 slot, as it falls to No. 2 with 154,000 (down 21 percent). Smith's "Stay With Me" dips 2-3 with 144,000 (down 12 percent), and Iggy Azalea's "Fancy," featuring Charli XCX, slips 3-4 with 123,000 (down 21 percent). Nico & Vinz's "Am I Wrong" climbs 8-5 with 114,000 (up 18 percent), Meghan Trainor's "All About That Bass" bumps 18-6 with 103,000 (up 61 percent), and Maroon 5's "Maps" falls 6-7 with 103,000 (down 2 percent).

Ariana Grande's "Problem," featuring Azalea, descends 5-8 with 100,000 (down 12 percent), Florida Georgia Line's "Dirt" moves 7-9 with 95,000 (down 3 percent), and Charli XCX's "Boom Clap" shifts 9-10 with 87,000 (down 5 percent).

Overall album sales in this past chart week (ending July 27) totaled 4.3 million units, down 2 percent compared with the sum last week (4.4 million) and down 9 percent compared with the comparable sales week of 2013(4.9 million). Year-to-date album sales stand at 137.8 million, down 15 percent compared with the same total at this point last year (161.2 million).

Digital track sales this past week totaled 19.4 million downloads, down 5 percent compared with last week (20.4 million) and down 16 percent stacked next to the comparable week of 2013 (23.2 million). Year-to-date track sales are at 674.9 million, down 13 percent compared with the same total at this point last year (775.4 million).

Next week's Billboard 200 competes with the same week in 2013 when: Robin Thicke's Blurred Lines debuted at No. 1with 177,000 and Five Finger Death Punch's The Wrong Side of Heaven and the Righteous Side of Hell, Volume 1 debuted at No. 2.
