CHART WATCH

There's no change this week atop either the singles OR albums chart, and Usher's still bagging bucketloads of sales of his single 'OMG' in the No.1 position. So many, in fact, that he's more than 8000 copies ahead of his nearest rival. Let's check out the charts;

SINGLES : We don't know about Bieber Fever, but the man who won the battle to sign the Bieb is powering away at the top of the ARIA singles chart again this week with his single 'OMG'. It sold over 25,000 copies again (25,600 to be exact) to remain in the No.1 position, a long way ahead of B.o.B. back in No.2 on 16,832 sales.
California Katy is up to No.3 with her newy 'California Gurls' (11,977 sales), with Yolanda Be Cool and Jason Derulo not too far behind (11,632 and 11,063 respectively).
The cast of Glee aren't going anywhere soon - and in their cover of Jessie's Girl, they have another top ten hit. It's up to No.8 this week, with David Guetta's latest 'Gettin' Over You' and Chiddy Bang's 'Opposite Of Adults' also following into the ten - at Nos.9 and 10 respectively.
Adam Lambert marches up again with 'Whataya Want From Me' - up four to No.15, but Brian McFadden's 'Just Say So' suffers an eight place drop - down to No.17.
ARIA finally changes the 'Travis' to 'Travie' as Mr.McCoy recored a 17 place rise with his new single 'Billionaire'. It's up to No.18 this week with 4447 sales in the bag, but Gaga and Bieber drop.
Could Scouting For Girls be headed to the top with their single 'This Ain't A Love Song'? The UK band achieved the feat in their homeland - and the track is still climbing down under, up six places to No.26 this week.
Ou Est Le Swimming Pool rises, while Enrique Iglesias breaks into the top 50 at No.32 with his new single 'I Like It' (2672 sales).
Amy Meredith is back into the top 50 mix with 'Lying', while Eurovision winner Lena scores the highest debut of the week with her single 'Satellite' - it's in at No.37 with 2121 sales.
Ironik & Chipmunk are in at No.41 with their Elton sampling 'Tiny Dancer' (1943 sales), while Angus & Julia Stone, John Butler Trio and T-Pain make top 50 re-appearances at Nos.43, 47 and 49 respectively.
Outside the top 50, N.E.R.D. and Nelly Furtado are making a run for it with their track 'Hot 'N' Fun', rising 22 places to No.52 this week, but the Glee Cast suffers a 25 place drop - down to No.53.
Lady Antebellum continues the climb with 'Need You Now' - up to No.59, the ace Pendulum remix of the ABC News Theme is in at No.64 (1354 sales) and Dizzee Rascal's 'Dirtee Disco' dances its way into the mix at No.68 (1305 copies).
Further down, Alicia Keys pops back in at No.82 with 'Empire State Of Mind Pt.II', the Glee Cast's rendition of 'Safety Dance' and 'The Boy Is Mine' find chart favour at No.91 (892 sales) and No.97 (796 sales) respectively, while there are re-emergences for Sia ('Clap Your Hands' at No.95), Operator Please ('Logic' at No.96), Miley Cyrus ('Party In The USA' at No.98 and Taylor Swift ('Love Story' at No.99).

ALBUMS : The second lowest sales week on the albums chart so far this year sees the cast of Channel 10's hit TV show 'Glee' maintain their grasp on the No.1 position this week, despite only selling 6201 copies of their 'Showstoppers' LP.
By the time we get down to the No.5 position (k.d.Lang's 'Recollection'), we're down to just 3534 copies and amazingly, just 2485 copies would've got you a top ten album in Australia this week.
With some discounting on best-ofs and popular recent albums, there's a swag of resurgences and re-emergences in the top 100 this week.
The cast of Glee benefits from a sub $10 price with their soundtracks (volumes two and one) rising to Nos.12 and 15 respectively.
The Sex & The City 2 soundtrack is the week's highest debut of the week - in at No.13 with 2199 sales, and Pink's 'Funhouse' also benefits from a bargain price, moving back up to No.14 (2192 sales).
Cat Stevens, Foo Fighters, Michael Jackson, Beyonce, Guns & Roses, Lily Allen - they all benefit from the nice price campaigns.
Local outfit Midnight Juggernauts make a No.20 debut with 'The Crystal Axis' (1670 sales), Lady Antebellum make a top 50 debut at No.36 with 'Need You Now' (1160 sales) and more re-emergences further down the top 50 from Mark Vincent, Phil Collins, Bruce Springsteen, The Doors, Madonna and Rod Stewart.
Even outside the top 50, the cavalcade of recent albums and best-ofs keep surging for the top, including those from Taylor Swift, Jessica Mauboy, Eurythmics, Roy Orbison, Neil DIamond, Crowded House, Meatloaf, Abba, Neil Young, Katy Perry, Green Day, Radiohead, Michael Buble and more.
They are, however, dotted with two debuts - the Black Sabbath best-of at No.58 (813 sales) and Catherine Britt's eponymous album at No.73 (724 sales).
