LOS ANGELES (Reuters) - Thousands of Amy Winehouse fans went to Rehab in the United States for a fresh listen to the songstress who died late last week, according to figures released on Tuesday. Record sales tracker Nielsen SoundScan said fans of the soul singer snapped up 50,000 copies of her CDs in the week ended July 24, compared to 44,000 units that were purchased in all other weeks of 2011. Her 2006 smash hit album, Back to Black, which includes the song Rehab, accounted for 37,000 of those units sold in the United States, which was the highest weekly total since March 2008. Winehouses debut album, 2003s Frank, chalked up 7,600 unit sales, Nielsen SoundScan said. Of the totals, more than 95 percent were digital downloads. Amy Winehouses father has revealed plans to set up a foundation in his daughters name to help people struggling with addiction. If you cannot afford a private rehabilitation clinic, there is a two-year waiting list for help, Mitch Winehouse said at the singers funeral. He said the 27-year-old had conquered her drug addiction and had been trying hard to deal with her drinking. He added she had been her happiest for years in her final days.
