After her entire album was leaked online in its unpolished, unfinished form before even being announced, Madonna has surprise-released six new tracks, Gigwise reported.

Two tracks from the forthcoming album had already leaked over Thanksgiving weekend, before the entire album leaked a week later. She revealed that they were 'unfinished demos stolen long ago' and sketches of what the album would become, but they've still spread like wildfire across the web.

She subsequently took to Instagram to voice her hurt and frustration at the situation.

"This is artistic rape!" she wrote. "These are early leaked demo's half of which wont even make it on my album the other half have changed and evolved. This is a form of terrorism. Wtf!!!! Why do people want to destroy artistic process??? Why steal? Why not give me the opportunity to finish and give you my very best?" The post has since been deleted.

She's now announced that the album will be called Rebel Heart, and is available to pre-order on iTunes alongside six tracks that are available to download now. Listen to the tracks below. 'Unapologetic Bitch' is particularly catchy, and the lyrics 'You'll never know how much your selfish bullshit cost me' seem apt.
