This new single from Canadian-born teen star, Justin Bieber, is his second to appear on the ARIA Singles Chart. The track sees Bieber team up with hip hop star and fellow Atlanta resident Ludacris. The track has already gone to No.3 in Bieber’s native Canada and to No.5 on the Billboard 100.  Bieber’s first charting single in Australia was One Time (No.30 Feb. ’10).

Without a doubt, the strangest title in the chart this week has come from this single by Canadian rapper-producer K-os. The track comes from K-os’ fourth album, Yes! It’s his first release to enter the ARIA Singles Chart. The song, which features rapper Saukrates and Nelly Furtado, samples Phantom Planet’s track California (best known as the theme tune from The O.C.). On the title of the song, K-os has explained that he considers Natalie Portman to be the best of the American ideal.

The fifth single from Natalie Bassingthwaighte’s debut album, 1000 Stars (No.1 Mar. ’09) gives her a fourth entry on the ARIA Singles Chart. Love Like This has been released in support of the AIDS Council Of NSW and their Wear It With Pride campaign leading up to the 2010 Mardi Gras. Bassingthwaighte has scored chart entries with Alive (No.8 Jan ’09), Someday Soon (No.7 Jan. ’09) and 1000 Stars (No.30 May ’09).

The sixth studio album from London electronica duo, Groove Armada, is their first in three years. Black Light follows on from 2007’s Schoolboy Rock (No.30 May ’07). Tom Findlay has said that the album features Groove Armada’s “darker side”. Appearing on the track Warsaw is Pnau, Empire Of The Sun and Teenager man Nick Littlemore. Groove Armada just wrapped up an Australian tour as part of the Big Day Out.

Returning to the chart is metal hero, film director and screenwriter Rob Zombie and his fourth studio album, Hellbilly Deluxe 2. Hellbilly Deluxe (No.37 Sept. ’98) was Zombie’s first solo album following the split of his band White Zombie in 1998 and this new album is its sequel. The album’s release was held back several times due to Zombie’s commitments as writer, director and producer of the film Halloween II, the sequel to his 2007 remake of classic horror film, Halloween.

After almost four years without an album release, Welsh band Lostprophets release their fourth studio album, The Betrayed. The time between this new release and that of Liberation Transmission (No.62 July ’06) saw the band facing trouble with labels and producers. It’s believed an albums-worth of material was recorded by the band but was scrapped before the groundwork for The Betrayed began. The Betrayed’s chart debut gives the band their highest peak on the ARIA Albums Chart.

Hailing from Dento, Texas, is indie quintet Midlake. The band who have released two previous studio albums, are making their ARIA Albums Chart debut with this, their third studio album.
