Pop star Sia has collaborated with Italian DJ Giorgio Moroder on a new track "Deja Vu".
The song is the title track of Moroder's first album in 30 years which will also feature appearances from Britney Spears and Kylie Minogue among others, besides the Australian singer/songwriter, reported Ace Showbiz.
On the upbeat track, the "Chandelier" hitmaker sings about waiting for her Mr Right and later falling for him over the '70s disco-inspired beat.
