Samsung has made a move into the music streaming space with Milk Music. It's a free service and offers a range of fine-tuning options as well as a novel interface.
The app is completely free and doesn't play ads to users. You don't need a login and once downloaded on to compatible Samsung devices it's ready to go. The jog-wheel offers a nice way to scroll through stations quickly or with more finesse. You can have up to nine genres on your dial at a time and fully customise what you have easy access to.
At this stage there's no indication from Samsung when the new service will be rolled out to other territories. Given Samsung is looking to compete directly with Apple's iTunes Radio we believe it'll be sooner rather than later.
