Samsung’s new Milk Music personal radio app has been downloaded 380,000 times since its release in early March, the company has announced. That tallies with the figure on Android’s Google Play store, which lists Milk Music as having between 100,000 and 500,000 installs. Not a bad start for a service that’s only available in the US for a handful of Samsung smartphones and phablets. Samsung’s Wonpyo Hong told the Wall Street Journal that for now, Milk will be a Samsung-only affair – “At the moment, we’d like to create an experience uniquely on our device because the fundamental core part of our business is selling hardware”. Meanwhile, the company has also let slip its plans to take Milk beyond its current free and ad-free incarnation. An infographic seemingly published by accident (and since taken down) revealed plans for a two-tier service: Basic will be free to users with ads, while Premium will be ad-free with “some exclusive features” for $3.99 a month. That will undercut rival Pandora’s subscription tier by a dollar, since Pandora One’s monthly price is rising from $3.99 to $4.99 for new subscribers.
