CHART WATCH

Another big week on the ARIA charts this week - and though our No.1 single remains the same for the second week in a row (Ke$ha's 'Tik Tok'), we have a new No.1 album. Take a bow, Mister Williams.

SINGLES : Ke$ha's debut solo single 'Tik Tok' strengthens it's hold on the Aussie singles chart this week, and with copies of the physical single arriving in stores early, it's sold 13,866 copies to remain on top for a second week. The Black Eyed Peas are in the No.2 spot again with 'Meet Me Halfway' (11,015 sales), while Jay Sean moves up to No.3 with 'Down' (10,015 copies), Vanessa Amorosi stays put at No.4 (8435 sales) and 3OH!3 with Katy Perry rises into the top five with 'Starstrukk', courtesy of a decent 7781 sales.
Lady Gaga slips to No.7, Britney's back up slightly and Rihanna scores the highest debut of the week with her new single 'Russian Roulette'. It debuts at No.11 on the back of 5550 sales.
The buzz around Robbie Williams' new album and forthcoming visit sees his track 'Bodies' back up four places this week - to No.14 with 3663 sales, while Jay-Z and Alicia Keys debut in the No.20 position with 'Empire State Of Mind' (2989 sales).
Michael Jackson's guitarist Orianthi bullets to No.23 with her debut single 'According To You' (2666 sales) and John Mayer rises six places to No.31 with 'Who Says' (1846 copies).
The Glee Cast can do no wrong - it seems everything they sing seems to end up in the ARIA top 100 - and this week it's 'Sweet Caroline's turn. The Neil Diamond cover is up from No.76 to No.37 with 1542 sales.
New to the top 50 are at No.39 - Jason DeRulo's 'Whatcha Say' (1519 sales), No.40 - Timbaland's 'Morning After Dark' (1462) and returning are Leona Lewis ('Happy' at No.44 with 1376 sales), Michael Buble ('Haven't Met You Yet' at No.46 with 1348 sales) and Beyonce ('Sweet Dreams' at No.47 with 1342 sales).
Outside the top 50 and Owl City's current US No.1 'Fireflies' seems to be finding favour with local audiences - it's gained an impressive 35 places this week to come in at No.52 (1296 sales), Ian Carey's made up the same number of chart places - from No.96 last week to No.61 this week - with 'Shot Caller' (1028 sales), Lily Allen's 'Who'd Have Known' moves up to No.66 (976 sales) and even though his album's not yet on the local horizon, Canadian teen star Justin Bieber's debut single 'One Time' debuts at No.82 with 739 sales.

ALBUMS : Was it going to be Bon Jovi, Vanessa Amorosi or even the Glee Cast that bagged the coveted No.1 spot on this week's album charts? It turned out to be neither, with Robbie Williams beating them all off with a stick to debut at No.1 with 'Reality Killed The Video Star'. But even though he debuted atop the Aussie albums chart, he didn't do it as convincingly and many would've thought. He sold a meagre 12,276 copies of his new album last week to nab the No.1 spot.
The Foo Fighters' greatest hits package, last week's No.1, slipped to No.2 with 11,470 copies sold in it's second week in.
The 'Volume 1' soundtrack to hit TV series 'Glee' debuted at No.3 with 9180 sales, while Bon Jovi debuted at No.4 with their new album 'The Circle' (8491 copies).
Also on the debut this week was Vanessa Amorosi and her new album 'Hazardous'. 6597 fans popped out to the shops last week to pick up a copy, on the back of the success of lead single 'This Is Who I Am'. Rod Stewart popped in just outside the top ten - at No.11 - with latest album 'Soulbook' selling 4735 copies and country star Lee Kernaghan saw his new album 'Planet Country' debut at (an unlucky for some) No.13 with 3610 sales.
The Beatles' limited edition boxset raced up the chart this week - 22 places higher at No.23 (1923 sales), while Slayer fans deserted them in their second week - down from No.9 last week to No.25 this.
Creed popped in at No.27 with new long player 'Full Circle' (1866 sales), The Doors and Britney both rose into places #28 and #29 respectively and the new 'Box Set' by the 12th Man sells 1624 copies to debut at No.34.
With heavy discounting and 'two for one' deals available at Australia's leading retailers, some classic albums and greatest hits packages have made their way back into the top 50. Bruce Springsteen's Greatest Hits, Abba's '18 Hits', Neil Young's Greatest Hits and Lily Allen's 'Alright, Still' just four to do so.
Beyond the top 50, Snow Patrol's retrospective 'Up To Now' debuts at No.54 with 1233 sales, Rammstein's album 'Liebe Ist Fur Alle Da' plummets 35 places to No.55, Kasey Chambers debuts at No.58 with 'The Little Hillbillies' project (1210 sales), Whitley's album drops from No.27 to No.65 and Matt Tilley's 'Gotcha Calls' charity album plunges from No.23 to No.67.
Five more top 100 debuts come courtesy of Carrie Underwood's 'Play On' at No.80 (944 sales), Bee Gees ('Ultimate Bee Gees' at No.87 - 860 sales), Orianthi ('Believe' at No.88 - 855 sales), Diana Krall (Best Of at No.92 - 840 sales) and Cat Stevens ('Tea For The Tillerman' at No.95 with 830 copies bagged).
