Teenage superstar Lorde went to number one last week with her debut Pure Heronie and there's a chance she could hold onto that spot for a second week. She'll be challenged by controversial American pop star Miley Cyrus, who Lorde recently knocked off from number one on the Billboard 100.
Riding a wave of 'twerking' controversy and the very public discussion of her sexualisation, Cyrus has had a money-can't-buy amount of publicity leading into the release of her Bangerz album. It's virtually opposite of Lorde's path, which so far has been focused on the music and the respect for her musical ability at such a young age.
Mauboy has also had a high profile couple of weeks with her placement on advertisements for the NRL Grand Final, which, like Lorde, has been a very respectful media campaign focusing on her talents. Her album Beautiful is still definitely in the hunt and makes it an intriguing three-way battle in this week's chart.
Outside of the top three American metal outfit Korn will look to debut in the top ten with The Paradigm Shift. Outside of that ten will be Something For Kate's frontman Paul Dempsey with Shotgun Karaoke, Busby Marou with Farewell Fitzroy, Saviour with First Light To My Death Bed, Panic! At The Disco with Too Weird To Live, Too Rare To Die!, Glee Cast's polarising Glee Sings The Beatles and Aussie rock legend Daryl Briathwaite's Forever The Tourist, which should enjoy a top 50 debut.
No surprises in this week's big movers, with Fleetwood Mac and ABBA enjoying another of their regular sales bumps with Greatest Hits and ABBA Gold respectively.
The midweek figures are also indicating that Lorde's The Love Club EP will enjoy a significant bump in the ARIA Singles Chart. The EP has enjoyed 22 weeks in the chart and is currently at 14, after peaking at two. Current number one Katy Perry's Roar will be hard to dethrone, however.
Other tracks experiencing sales bumps include Avicii's Wake Me Up (currently 11), Ylvis' viral track The Fox, Jason Derulo's Marry Me and Zedd featuring Hayley Williams' Stay The Night.
UK soft rock favourite James Blunt will likely be the highest debut with Bonfire Heart, followed by Nathaniel Willemse's You, Avicii's Hey Brother, Havana Brown's new track Warrior, Justin Bieber's Heartbreaker and Mike Will Made It featuring Miley Cyrus, Wiz Khalifa and Juicy J's 23.
This week's new sets include local acts Born Lion, The Getaway Plan, Morning Harvey, Fraser A Gorman and more.
