It hasn’t been long since Samsung launched Milk Music – a free Internet radio service without ads. And the Korean electronics giant has already revealed that it is “soon” going to add a price tag with an all new premium service plan.

According to an infograph about Milk Music from Samsung, Milk Music users who wish to avoid corporate messages interrupting their listening will likely be required to pay $3.99 per month.

Samsung also noted that premium consumers other than enjoying ad free streaming experience will also get some exclusive features.

It’s unclear when the premium subscription plan will be rolled out for purchase; however, Samsung said it is going to retain the ad-free offer for early adopters and will introduce ads only after a certain period of time.

Milk Music offers users with access to more than 200 radio stations completely free of charge and without ads. Samsung through the infograph has hinted that the free version of the service listed as “Basic” may “soon” include advertising. The company has also revealed the “Premium Service” subscription options that will be available soon.

The new plan falls in line with Slacker’s $3.99 monthly subscription, which allows ad-free offline playback and unlimited skipping along with some exclusive stations. Slacker, the company’s music service partner in launching Milk Music, also offers a $9.99 top-tier that lets users select songs/albums on demand, create custom playlists and more.

This move hints that the company is planning to expand its internet radio service globally and perhaps even to other devices.

Milk Music is currently available to only US-based Samsung customers and supports only a handful of Samsung Galaxy devices including the Galaxy Note II, Galaxy Note 3, Galaxy S III, Galaxy S 4, and Galaxy S5.

[Update] We have received an emailed statement from Samsung: “We’re continuously looking at ways we can enhance Milk Music with new features to deliver the best radio-listening experience for our consumers. We don’t have additional information to share right now, but stay tuned.”
