Hot off the launch of Beats Music, does the world need yet another music streaming service? Samsung's about to find out. In January, Samsung actually shut down its streaming service for US customers — but now, it's coming back as something completely different. Today the company's introducing Milk Music, a free streaming radio service designed to get people listening to music from any genre in just a few seconds. And for the immediate future, there are no ads to interrupt listening. Samsung says that Milk Music is an effort to solve common problems in what's become a sea of streaming music services. Those include too many ads and interruptions, long and arduous setup processes, and songs that play too frequently on a given station, says Chris Martinez, Samsung's director of services planning.
