US Justice Department to investigate digital music pricing

A Justice Department spokeswoman, Gina Talamona, said that antitrust enforcers are 'looking into the possibility of anticompetitive practices in the music-download industry.'

As part of the inquiry, which doesn't appear to be a criminal investigation, all four companies have either received so-called civil investigative demands, similar to subpoenas, or have been notified they will be receiving them soon, the Journal said. The investigative demands were sent out Monday.
