I actually didn't say whether it was a civil or criminal case, but that's actually moot since almost all of the "sauce for the goose" cases on whose petard people are proposing hoisting Sony were also civil cases. Those are often the ones where the studios factored into their damages claims the number of times a track was downloaded *from* the plaintiff via Kazaa, eMule, BitTorrent or whatever, and then applied an insane multiplier to arrive at their "punitive damages" figures. Using Google Play doesn't change things. Sure, the singer's studio could issue a take down under the DMCA, but where's the fun and profit in that, when Sony is *also* infringing copyright by distributing the track without a valid license - exactly the same setup that many of the plaintiffs in those civil cases brought by the studios were sued for?
Legal issues aside it's all going to be moot anyway. Sony won't want a DMCA takedown interfering with the money the film is currently making them, and they definitely won't want to face an embarrassing copyright infringement case. If all had gone to plan, Sony would have paid the artist's studio some money - most likely either a lump sum or a figure derived from ticket sales - they'd have taken their cut and paid her the rest, and that's almost certainly still the way things will go. So, some studio execs (maybe lawyers, maybe not) will almost certainly have a chat in the next few days, a number will be thrashed out, some money will change hands, and that will be the end of the matter.
