As the news of Amy Winehouse's premature death still sinks in, record sales of her "Back to Black" album have skyrocketed, leaving her record company, Universal Music, scrambling to find as many unreleased recordings, live or in the studio, as they can.

Universal Music issued the following statement Sunday following the death of Winehouse:

"We are deeply saddened at the sudden loss of such a gifted musician, artist, performer and friend. Our prayers go out to Amy's family, friends and fans at this difficult time."

At the moment, she is dominating the front page of iTunes, with Back to Black at #1, and her first album, Frank, at #6.

"After Michael Jackson died, his CD went to number one again, "a music insider told the Huffington Post. "And he continued to set the charts on fire with a stash of unreleased music that went on to earn his estate and company millions. The same will happen with Amy.

"The difference between Amy and Michael is that Michael was always recording and writing," the insider said. "Michael has a vault of unreleased material and was always experimenting with new sounds. Amy, on the other hand, didn't produce anywhere near the volume that he did. At the moment, all they believe they have is a few new songs and several songs that didn't make it onto her debut CD."

But this appears to have become the standard.         

In 1967, Otis Redding's "Dock of the Bay" was released. A month after John Lennon's 1980 murder, "Woman" was released. And Tupac's label has put out numerous albums since his 1996 death.

While it is unknown what Winehouse's label will release, one track is surely forthcoming. The 27-year-old recorded "Body and Soul" with Tony Bennett for his upcoming "Duets II" album at Abbey Road Studios in March.

Bennett called Winehouse "an artist of immense proportions."

Winehouse died at her London home Saturday. An autopsy into her death was being held at St. Pancras Mortuary Monday afternoon.
