Samsung Milk Music launched in March as a free streaming music service for the company’s smartphones. It works really well at providing free access to 200 streaming radio stations that are powered by Slacker Radio, but one of the best features is that it didn’t serve up any ads. Now, Samsung is going to start offering some premium pay-for features for folks who want a bit more, but that launch may coincide with the addition of ads to the free model.

The company recently posted an infographic highlighting some of the features of Milk Radio, like the custom dial we like so much, pre-cached music for quick-tuning without any delay, and some of the customization features. However, at the bottom of the infographic Samsung has two services listed: basic and premium. The basic service is what we already have, but now says “free to users with ads.” Samsung says the premium version will offer ad-free listening and “some exclusive features” for $3.99. Bummer — so Milk Music may lose one of the features that made it stand out.

Samsung has announced its intentions to deliver new albums straight to Milk Music, and it seems like the company may allow premium users to listen to new content earlier than folks on the basic plan, too. TechnoBuffalo reached out to Samsung for explanation but a spokesperson was not immediately available. We’ll update this story when we find out more.

Update: “We’re continuously looking at ways we can enhance Milk Radio with new features to deliver the best radio-listening experience for our consumers,” Samsung said in a statement to TechnoBuffalo. “We don’t have additional information to share right now, but stay tuned.”
