That issue was settled in May when the record labels agreed to drop their controversial pricing agreements with retailers. The record labels did not admit wrongdoing. The new lawsuit underlines the increasing disputes over the way the record companies have used their market domination in recent years. Music-swapping service Napster, which is being sued by the record industry for copyright infringement, has contended that the big labels have abused their copyright power and have thus lost the ability to defend those rights in court. A federal judge, however, virtually ignored that argument in court last month, largely siding with the record industry against Napster. Defendants in today's suit include Capital Records, Sony Music Group, Bertelsmann's BMG Entertainment, Seagram's Universal Music Group and Time Warner's Warner Music Group, along with retailers Musicland, Transworld and Tower Records.
