Streaming service Grooveshark has been seen as down and out for the count following its copyright court battle with major labels. But to mix sporting metaphors, the company may have one last hail-mary pass in it: a standalone app for its Broadcasts social radio service. The company says its “first compliant app” will launch in January, costing $0.99 a month to stream personal radio channels curated by other users, with text chat built in. It’s Pandora meets WhatsApp, in other words: something CEO Sam Tarantino tells the Wall Street Journal could “change the ballgame”. Not least because Grooveshark’s new app will be licensed from the get-go without the need for individual deals with labels and publishers, through statutory rates. “We’re trying to show that we’re doing everything we possibly can to be a legitimate player here,” said Tarantino. Our question here is less about whether Grooveshark can go legit, and more about whether post court battle, it has the funding to make Broadcast a success, against competition from Pandora, iTunes Radio and the free mobile tiers of Spotify and Rdio among others.
