Expect the seasonal song to climb up the charts fast in the next four weeks (yep, Xmas is now four weeks away!).

Surpassing the three weeks racked up by 'Shake it Off' (Sept 2014), 'Blank Space' (Nov-Dec 2014) and 'Bad Blood' (Jun 2015),

All the action from the ARIA Singles Chart.

For the first time this decade a Taylor Swift song has held on for a second week at the top of the Australian Singles chart, as "Anti-Hero" gains another week at #1.

As expected...

Swift's new album 'Midnights' dropped on Friday.

'Unholy' is now Sam Smith's longest-running #1 song in Australia.

Smith's second #1 single in Australia and Petras's first.

Smith’s second #1 single in Australia.

Holding onto the No.1 spot for a second week is the David Guetta and Bebe Rexha dance track "I'm Good (Blue)", with the song also taking the top spot in England and Canada this week too.

She first charted in Aus in 2010 on the Will.i.am track 'Check It Out'.

It's also the first chart entry for Britney in six years.
