Talk about a company that can't stay out of the courtroom. Yet again, we've got XM headed back for another round of sticky legal action, and while we highly doubt the firm's lawyers are done digesting the NMPA suit from less than a month ago, now it's being forced to deal with an Arkansas man's allegations in US District Court. Matthew Enderlin is apparently quite upset with XM's "false claims of commercial free music," as he adumbrates that the channels actually do include "promotional and advertisement segments." Unsurprisingly, XM has said the suit is "without merit," but Mr. Enderlin isn't backing down; au contraire, he's actually seeking to "have the suit certified as a class-action suit so all XM Radio customers can be considered plaintiffs." Bet you weren't expecting to join in on the fun yourself, eh?
