Amy Winehouse Albums Take Multiple Slots On The Charts

Almost immediately following her tragic death last week, Amy Winehouse's albums have begun tearing up the music charts in America, Canada and the UK.

As of Monday morning, "Back to Black" had hit number one on the iTunes charts, with thousands of new downloads, and "Back to Black: B-Sides" had also landed in the top ten.

Perhaps ironically, the album that Winehouse's "Black" replaced on the iTunes chart was Adele's "21." On Monday, Adele wrote an extensive blog post about Winehouse's legacy, noting that the troubled singer had "paved the way for artists like me and made people excited about british music again."

Though the full effect of the spike in sales won't be made clear until next week, "Back to Black" already made an impression on the physical UK album charts, jumping to number 59 in only two days -- a 299% increase in sales.

UK's Official Charts Company managing director Martin Talbot said in a statement that he expects an even greater surge in the coming days. "Such a demonstration of her popularity is the best tribute the British public can pay to this extraordinary British talent."

There is a lot of talk about a posthumous Winehouse album being released -- one she had been working on for some time -- though no one at Winehouse's label can confirm how close the album was to completion. Chas Newkey-Burden, the author of "Amy Winehouse: The Biography," told DigitalSpy that the release of an unfinished album would only "muddle her legacy."

"She obviously had doubts about it," he said, "So any posthumous album would raise the question of whether she would have been happy with it.

Winehouse's "Back to Black" was nominated for multiple Grammy awards in 2008 and peaked at the number two spot on the Billboard charts that same year.

The singer's death is still being examined, as an autopsy performed on Monday was deemed inconclusive. Toxicology reports will be released in 2-4 weeks.
