The top five on the albums chart are completely unchanged, while over on the singles side of the draw, Short Stack debut with a big pop at No.4. But without big physical singles sales, they'd have been down at No.10. So let's check out who sold what on this week's slightly belated Chart Watch.
SINGLES : Rihanna's still in the No.1 position, but figures are slightly softer on last week - in fact she narrowly scraped out on selling that magical 20,000 mark, but hey - in excess of gold sales within two weeks is a pretty decent effort, so who's complaining. 'Only Girl (In The World)' sold another 19,958 copies this week.
The battle for the No.2 spot is heating up, with Taio Cruz' 'Dynamite' (on 17,719 copies) outselling Bruno Mars' 'Just The Way You Are' by a mere 40 copies.
As we made mention, Short Stack explode onto the chart at No.4 with their brand new single 'Planets', but without their mad fans rushing into stores and snapping up 4357 copies of the physical single across the country, it would be all the way down at No.10. All up, it sold 13,891 copies.
B.o.B is also making waves with his new single 'Magic', which enters the top five for the first time at No.5.
Barbra Streisand is in the Aussie singles chart... But not the lady herself - the song bearing her name by Duck Sauce. The club banger comes in at No.12 with 8892 first week sales, and the Potbelleez are now in the top 20 with their track 'Hello'.
Glee's version of 'Empire State Of Mind' moves from No.40 to No.20 and Zoe Badwi's 'Freefallin' is up to a new peak of No.23.
Glee's 'Telephone' is up 15 spots, their version of Travie McCoy's 'Billionaire' is up 16 spots and Scarlett Belle hit the No.37 spot with 'Freak Tonight' (2889).
Justice Crew surges to No.39, Paramore is back in the top 40 with 'The Only Exception' and Mumford & Sons' single 'Little Lion Man' re-enters the top 100 at No.48 (2150 sales).
Outside the top 50, a big move from Lady Gaga & Beyonce's 'Telephone' - up 16 spots to No.52 and some more Glee action with their version of Britney's 'Toxic' hitting No.53 (1899 sales).
James Blunt's new single 'Stay The Night' spends its first week on the Aussie singles chart in the No.56 position (1734 sales) and Glee are back again at No.60 with their version of Paramore's 'The Only Exception' (1638 sales).
Mark Ronson's 'The Bike Song' debuts at No.66 (1530 sales), Adam Lambert's new single 'For Your Entertainment' debuts at No.69 (1494 sales), Kasey Chambers' 'Little Bird' is in at No.82 (1237 sales) and The Ting Tings make a splash at No.83 (1227 sales).
The Glee Cast are in again - at No.93 - with their version of 'Me Against The Music' (1012 sales) and Selena Gomez & The Scene are in the singles top 100 at No.100 with 'A Year Without Rain' (943 copies).

Mark Ronson's album 'Record Collection' is the highest new debut for the week. It's in at No.6 with 3725 first week sales, while Birds Of Tokyo and Angus & Julia Stone also surge.
Soundgarden's best-of 'Telephantasm' debuts in the No.20 spot with 1541 first week sales and Eric Clapton's new LP has his name written all over it at No.21 (1509 sales).
Mumford & Sons' album moves up 16 places, Tim McGraw's heading in the other direction and Beccy Cole's album 'Preloved' makes its debut at No.32 (1021 sales).
Michael Franti is in at No.34 with 'The Sound Of Sunshine' and 1015 sales and John Legend's new LP pops in at No.42 (957 copies).

Interpol's album, meanwhile, drops 28 spots to No.50.
Outside the top 50, Serj Tankian's album 'Imperfect Harmonies' debuts at No.56 (695 sales), Vanessa Amorosi's album 'Hazardous' re-enters the top 100 at No.59 and Robyn's 'Body Talk Pt.2' is in at No.68 (584 copies).
