PopUps: 14 More Madonna Songs Leak

Days after Madonna released six tracks on iTunes in response to more than a dozen of her songs from her upcoming album "Rebel Heart" leaked online, an additional 14 tracks of demos have made their way on the web, the New York Times reports.

The newspaper reports on Tuesday night, 14 new songs leaked online, including tracks called "Tragic Girl" and "Nothing Lasts Forever." There are reports that one of the newly leaked songs features Pharrell Williams. In total, there are at least 28 new songs that have popped up on the Internet without the Queen of Pop's permission.

"Obviously there is a person or a group of people behind this that were essentially terrorizing me," Madonna told The Guardian earlier this week before the Tuesday leak. "I don't want to sound alarming, but certainly that's how I felt. It's one thing if someone comes into your house and steals a painting off your wall; that's also a violation, but your work as an artist, that's devastating."

Last week, Madonna, 56, was furious after a batch of tracks, which she called unfinished and demos, leaked online, and she labeled the incident (in a now deleted Instagram post) "a form of terrorism" and "artistic rape." She said the songs were incomplete and not ready to be shared with her fans.

To respond to the leaks, Madonna officially gave her album a name, "Rebel Heart," a release date, March 10, and put up six songs on iTunes.

"I was hoping to release my new single 'Living for Love' on Valentine's Day with the rest of the album coming in the spring," Madonna said in a statement. "I would prefer my fans to hear completed versions of some of the songs instead of the incomplete tracks that are circulating. Please consider these six songs as an early Christmas gift."

The NYT reports Madonna has yet responded to the new leak. Maybe six more songs?
