The singer's "Back to Black" album has sold 37,000 copies since she died on Saturday.
That's more copies than the album has sold in the last three years, and puts /*Winehouse*/ at No. 9 on the Billboard list of top selling albums.
Most of the sales were digital downloads. The most downloaded Winehouse song? Her most famous one, "Rehab."
The 27-year-old Winehouse died of unknown causes at her London home last weekend. She had struggled with drug and alcohol addiction for years.
