Sia Heads Back Up US Chart

In its 18th week in the US Hot 100, Sia and David Guetta's collaboration Titanium moved back up to number seven this week.

The track which peaked at seven some weeks ago before falling and holding at number eight, regained traction this week and was highlighted as a bullet performer as Titanium moved back up to its peak position again this week (now sitting behind fellow Australian Gotye who holds at six with Somebody... - also this week his Making Mirrors album bounced back up the US charts to 46 in its 32nd week in).

The track also features on the Now That's What I Call Music Vol 43 compilation which debuted at number one on the US album chart this week.

According to Billboard, Sia is currently working with producer Greg Kurstin, of Bird & The Bee, who recently co-penned Pink's comeback smash Blow Me.

Fellow Australians Nervo also continued making a dent in the US charts this week as their hit You're Gonna Love Again moved from 15 to 12 on the Dance/Club Play Chart.
