Katy Perry and Luke Bryan have made chart history in the U.S. by landing half-million-selling releases at the top of the Digital Songs and Billboard 200 album charts on the same day for only the second time in history.

Bryan's Crash My Party debuts at number one on the albums chart with 528,000 first-week sales, while Perry's new single Roar has crashed in at the top of the Digital Songs list with 557,000 downloads.

The only other time that a download song and an album have sold each 500,000 in the same week was at Christmas, 2009 when Ke$ha's TiK Tok and Susan Boyle's I Dreamed a Dream album both sold in excess of 500,000.

Crash My Party is Bryan's second number one album - he took Spring Break... Here to Party to the top spot in March (13) - and it becomes the biggest first-week seller for any country male artist since Tim MCGraw's Live Like You Were Dying in 2004.

Meanwhile, Perry's latest hit becomes the third-biggest debut for a digital song - only FloRida's Right Round and We Are Never Ever Getting Back Together by Taylor Swift have outsold Roar.

The song ranks higher than Lady Gaga's comeback tune Applause, which debuts at three on the Digital Songs chart with 218,000 downloads sold. Bryan scores a top five new entry in that countdown as well - his That's My Kind of Night enters at five with 164,000 sales.

Katy Perry's Roar has proved no match for Robin Thicke's Blurred Lines on the mainstream singles chart, however. It shoots up from 85 to two on the new Hot 100, just behind the singer's summer anthem, which lands an 11th week at number one. Lady Gaga's Applause debuts at six.
