LCD Soundsystem frontman JAMES MURPHY will never forget the time he worked with Britney Spears - because the pop superstar walked out on him. Murphy and Spears briefly collaborated on songs the singer was planning to include on her 2003 album IN THE ZONE. Murphy remembers, "It was very strange - we were both lying on the floor, head-to-head, working on lyrics in a notepad. "She seemed eager to please, but it went nowhere. She went to dinner and just never came back."
