It's official: 5 Seconds Of Summer have conquered our hearts ... and wallets. The Australian pop-punkers put a giant exclamation point on their huge, um, summer by smashing into an easy #1 debut for their self-titled first studio album.

#1 Looks So Perfect

The "Amnesia" rockers sold 259,000 copies of the album, according to figures provided by Nielsen SoundScan, giving them the third-biggest debut of the year so far. the full-length easily beat the first week sales for the group's She Looks So Perfect EP, which moved 143,000 units earlier this year. And, according to Billboard, the healthy open is the largest for a group in nearly eight years, since Daughtry's self-titled debut came in on sales of 304,000 in November 2006.

It's also the biggest debut by an Australian act in the entire SoundScan era (which began in 1991).

Just below, the still-moving Frozen soundtrack was up three spots to #2 (37,000) knocking last week's #1, "Weird Al" Yankovic's Mandatory Fun, down to #3 as sales drooped by 68 percent to 33,000. Veteran rapper Common hit #6 with Nobody's Smiling (24,000) in a top 10 filled with albums that saw sales drop-offs from the week before.

Jason Aldean Burns It Down

Jason Aldean's "Burnin' It Down" shot up into the #1 spot on the Billboard Digital Songs chart (184,000) for his first digital #1, making MAGIC!'s ride at the top a short one as "Rude" fell a spot to #2 (154,000).

While Sam Smith's "Stay With Me" (#3, 144,000) and Iggy Azalea's "Fancy" (#4, 123,000) each slipped a spot, Nico & Vinz's summer smash, "Am I Wrong," ticked up three notches to #5 as sales increased by 18 percent to 114,000.

Bass, Bass, Bass!

With all that hanging around, it was "All About That Bass" for newcomer Meghan Trainor, as her debut single was up 12 spots to #6 thanks to a 61 percent increase in sales (103,000).
