The last chart of 2013 sees a new No 1 in the form of Jason DeRulo's Trumpets. It has risen from No 3 last week to become the American's third chart-topping single in Australia.
Trumpets also becomes DeRulo's second No 1 for the year. His track Talk Dirty debuted at the top here on August 19, staying at No 1 for a week.
DeRulo's first Australian No 1 was In My Head, which hit the top spot in February 2010 and stayed there for three weeks.
Trumpets becomes the 1013th No 1 single in Australia (1940 to 2013) and the 451st for ARIA, plus the 17th and final chart-topper for 2013.
There has never been a trumpet-titled song at the top before in Australia. For the record, the last song title to feature the word was Rizzle Kicks and Down With The Trumpets (HP-52) from September 2012.
The song also becomes the 14th No 1 for the Warner Brothers (direct) label.
Trumpets also becomes the 663rd No 1 single by an American artist in this country.
The last time the final week of year featured a new No 1 single was December 27, 2010, when Who's That Girl by Guy Sebastian and Eve started a two-week broken run at the top.
Pharrell Williams moves up two places to a new peak of No 2 with Happy. That pushes down Rude by Magic! to No 3, while former No 1 All of Me, by John Legend, drops to No 4 after three weeks at the top.
Two duets remain in the same positions this week: The Monster, from Eminem and Rihanna, is at No 5, followed by Timber, from Pitbull and Ke$ha.
Guy Sebastian's Like a Drum is back up a couple of places to No 7, and Avicii's Hey Brother remains at No 8.
On the albums chart, Michael Buble has held on for a third consecutive week with Christmas, giving the album its twelfth accumulated week at the top.
However, given the seasonal nature of the content, it's unlikely Christmas will hold on to the top spot next week.
Christmas becomes the equal third longest run at the top for 2013. (Buble's album To Be Loved spent five weeks at No 1 from April 22, and Pink notched up four weeks with The Truth About Love from three different runs between July 22 and September 9. The other album to achieve three weeks at the top was Bruno Mars' Unorthodox Jukebox back in January.)
Katy Perry's Prism jumps back up three places to No 2, which pushes the self-titled album for Beyonce down a place to No 3.
Also down a spot are The Twelfth Man's Willy Nilly and Human Nature's Christmas Album, now at No 4 and No 5 respectively.
One Direction and Taylor Henderson remain at No 6 and No 7, and Eminem is back up a place to No 8 with The Marshall Mathers LP 2.
New Zealand teenager Lorde climbs back up a spot to No 9 with Pure Heroine.
Fleetwood Mac return to the Top 10 at No 10 with 25 Years - The Chain, the album notching up its tenth week inside the top ten.
The self-titled album for X-Factor 2013 winner Dami Im leaves the Top 10 after five weeks (having enjoyed one week at the top): it's down three places to No 11.
