Steal Sia's new track, which in turn may be stolen from Aguilera.

The buttery voice and snazzy reverb of Australia's own Sia is back, and this time she will undoubtedly become a household name, on her own.

Even though her monster single "Breathe Me" blared through the cracks of every angsty art student's dorm room in 2005, Sia had TV to thank for that momentary success. After that track closed out HBO's "Six Feet Under," some of her other songs began to pop-up on ABC's "Private Practice" and FOX's recently cancelled "Dollhouse."

But her latest song, entitled "You've Changed," leads me to believe her newer, more dance-tacular sound, is prime for popular picking.

The fast-paced, bell-ringing, Motown-infused “You’ve Changed,” is the first track to be released from her upcoming April 2010 album "We Are Born." After playing the song a few times, I remembered that Sia was one of the artistsChristina Aquilera was collaborating with on her new CD. Could it be that Sia got a little motivation from X-tina? Give it a listen and decide for yourself below.
