- The condition of Argentine rocker Gustavo Cerati has improved since he underwent surgery to remove a deadly blood clot in his brain last week. The director of the Caracas medical center where Cerati is hospitalized said Friday that the 50-year old musician does not have neurological damage. Fans of the popular singer were shocked last weekend when he suffered a mini-stroke following a concert in Venezuela. Cerati has been hospitalized for over a week and undergoing treatment.

- Billboard reports that iTunes continues to dominate the music retail market, accounting for over a quarter of all music sales in the U.S. last year. That's more than twice what the Apple retailer sold in 2007 (12.7%) and double the market share of former top dog Wal-Mart (12.5%).

- File under "totally lives up to its horrific potential": Liza Minnelli's cringeworthy cover of Beyonce's "Single Ladies," straight from the "Sex and the City 2" soundtrack. Hay caramba! Love it? Hate it? Think it should be the new Rickroll song? Leave your thoughts in the comments.
