CHART WATCH

While the top three may have remained unchanged over on the ARIA singles chart this week, it's a big No.1 debut on the ARIA albums chart. It's a day late due to the Easter weekend, but here's this week's chart watch.

SINGLES : As mentioned, the top three positions remain unchanged this week, with Train still stationary at stop No.1 with their single 'Hey, Soul Sister'. In fact, the track further strengthened it's grip on the top spot, increasing sales to 21,937 copies.
Jason Derulo holds at No.2 with 'In My Head' (14,409 sales), while Lady Gaga (with Beyonce) is still in at No.3 with 'Telephone' (14,254 sales).
A massive debut at No.4 though for Kevin Rudolf - his new single, which features appearances from Birdman, Jay Sean and Lil Wayne, sells 12,424 copies in it's first week - a massive result. Rihanna and David Guetta suffer from Kevin's debut, both dropping one place, while Richard Vission storms his way into the top ten - at No.7 - with 'I Like That' (9493 sales).
Justin Bieber continues his march towards the top with 'Baby'. It's up two more places to be one spot outside the top ten, while B.o.B moves up a further eleven places to No.14 with 'Nothin' On You' (7373 sales).
Adam Lambert's up again to No.16 with 'Whataya Want From Me' (6818 sales), Florence & The Machine is up to No.17 with 'You've Got The Love' (5696 sales) and Alicia Keys moves up to No.18 with 'Put It In A Love Song' (5514 sales).
Further down, there's a decent move from Sean Kingston's new single 'Eenie Meenie'. With Justin Bieber guesting, the track moves up 19 places to No.30 (3444 copies).
A big move too for Chiddy Bang, who moves into the top 50 for the first time with 'Opposite Of Adults' (No.36 with 2732 sales).
There's a debut for the John Butler Trio at No.38 - their new single 'Close To You' sells 2600 copies in it's first week, just beating out previous single 'One Way Road' which re-emerges two spots lower with 2479 sales.
Newton Faulkner re-emerges in the top 50 at No.44 (No.92 last week), while Lady Gaga debuts at No.49 with 'Alejandro' (1902) and Rob Thomas debuts in the top 50 at No.50 with 'Mockingbird' (1884 sales).
Outside the top 50, Goldfrapp gets some chart love with 'Rocket'. It's in at No.55 with 1794 sales - could it break into the top 50 next week?
Guy Sebastian's also moving up with his new single 'All To Myself'. Another 15 place gain this week sees it rise to No.56 (1727 sales).
Vanessa Amorosi debuts at No.65 with 'Mr.Mysterious' (1424 sales), La Roux's in at No.79 with 'I'm Not Your Toy' (1164 sales), Counting Crows are in at No.81 with 'Colourblind' (1134 sales).
Biggest drop for the week is for Gyroscope - down 40 places to No.72 with 'Some Of The Places I Know'.

ALBUMS : Another new album for the John Butler Trio - another No.1 debut. JBT's new album 'April Uprising' becomes the band's third successive album to debut atop the ARIA album chart - and with relatively healthy sales. 'April Uprising' sold a respectable 14,348 copies for its No.1 spot.
Lady Gaga holds steady at No.2 with 'Fame Monster' (9243 sales), Angus & Julia Stone move down the way to No.3 (6555 sales) and Mumford & Sons drop just the one spot to No.4 with 'Sigh No More' (5383 sales).
Florence & The Machine's 'Lungs' almost matches its highest point so far - rising back up to No.9 with 2738 sales and Ke$ha's 'Animal' is also on the move back up - to No.12 with 2591 sales.
Evemore jumps another ten places with their eponymous set. It debuted at No.50 a fortnight ago, jumped to No.40 last week and to No.30 this week (at this rate, we could see them topping the chart in three weeks time).
Newton Faulkner is back in the top 50 at No.39 with 'Rebuilt By Humans' (844 sales), so too Kings Of Leon ('Only By The Night' at No.40 with 840 sales), Miley Cyrus, Vampire Weekend, Lady Gaga, Pink and Michael Jackson.
Outside the top 50, a slight move for Vanessa Amorosi's 'Hazardous' - up 18 places to No.59 (656 sales), Guy Sebastian's up to No.66 with 'Like It Like That' and Justin Bieber's 'My World 2.0' debuts at No.94 with 464 sales.
