A desperately low sales week over on the albums chart, with less than 7000 copies required for a No.1 album. But on the singles side of things, a different story as Brian McFadden scoops the pool.
SINGLES : There'll be some very happy people down at Universal Music's head office this morning, with champagne corks popping over Brian McFadden's No.1 single debut this week. Brian did rather well too - selling an impressive 20,739 copies of his new single 'Just Say So' to bag the top spot.
Train has departed platform No.1, dropping to No.2 this week with their track 'Hey, Soul Sister'. But the sales numbers are still quite impressive - another 17,208 copies in the kitty.
Richard Vission maintains the No.3 spot with 'I Like That', Jason Derulo drops to No.4 with 'In My Head' and Adam Lambert pops into the top ten - at No.5 with 'Whataya Want From Me' (11054 sales).
Lady Gaga's Aussie tour pays dividends for new single 'Alejandro' (along with some good use on the promos for Channel 10's 'So You Think You Can Dance'), with 10,921 people snapping the track up last week, making it move from No.28 to No.6 with a bullet.
Usher also gets a top ten placing - at No.10 with his new single 'OMG' (8767 sales).
Further down, Jason Derulo scores another top 20 hit with new track 'Ridin' Solo'. It's in at No.18 this week with 4478 sales in the bag. Just outside the top 20, Chiddy Bang is making their move - up 11 places to No.25, while Taio Cruz debuts in the No.29 position with 'Break Your Heart' (3244 sales).
Vanessa Amorosi finally sees some bigger top 50 love for her new single 'Mr.Mysterious'. On the back of her appearance on the reborn 'Hey Hey It's Saturday', the single jumps 16 places to No.34.
More top 50 debuts come from David Guetta ('Gettin' Over You' at No.43 - 2059 sales) and Operator Please ('Logic' at No.47 with 1800 sales).
Outside the top 50, Gyroscope make a big move with their new single 'Some Of The Places I Know'. It's up an impressive 35 places to No.60, while Jet moves back inside the top 100 (also on the back of their 'Hey Hey' appearance) at No.62 with 'Seventeen'.
Damien Leith finally gets some chart love for his new single 'Forgive, Forget'. It debuts at No.65 with 1204 sales, after it's use in Channel 9 promos.

ALBUMS : Over on the albums side of things, Lady Gaga maintains the No.1 position with 'The Fame Monster', despite depressingly low sales figures. Expect things to pick up slightly in the lead-up to Mother's Day. Gaga sold another 6902 copies of her album this week.
JBT holds steady at No.2 with 'April Uprising' and if just 12 more people had purchased Gyroscope's new album 'Cohesion' last week, they'd have had the No.2 position instead of JBT. 5561 copies for JBT, 5550 for Gyroscope.
Subo's postponement of her Aussie visit came too late in the week to affect sales for 'I Dreamed A Dream' - it moves back up five places to No.4 (5140 sales), with Slash dropping to No.5.
Second highest debut for the week comes courtesy of MGMT and their new set 'Congratulations'. It's in at No.9 with a lowly 3403 copies in the bag.
Laura Marling is heading back up the charts with her album 'I Speak Because I Can' - back to No.16 this week with 1842 sales.

Cheryl Cole adds a top 40 Aussie album to her top ten Aussie single success. Her album '3 Words' is in at No.31 with 1037 sales for it's first week, just one place (and 24 sales) ahead of James Reyne's new album 'TCB'.
