As the story goes, Beats acquired the music streaming service MOG in 2012… and 18 months later, we’re days away from the launch of Beats Music — based on MOG, with custom interface, a few clever new additions, and day 1 availability on Sonos. Of course, the headphone company is banking on their brand to drive subscriptions in a way largely unfamiliar competitors like Rdio can’t. Interestingly, Beats appears to forgo the traditional streaming-only plan in the $4 – $5 range and only offer the $10 ad-free tier, that includes the ability to create and download custom playlists. Further, Beats offers a genre-based presentation and curated playlists – perhaps similar to Slacker, which I’ve successfully replaced Sirius XM with nearly a month ago. Given the small investment of cash, I’ll certainly check Beats Music out for at least month. But luring a percentage of folks like me away from the Spotifys of the world isn’t enough, and I assume their intention is to take this mainstream. And we expect a variety of product and service tie-ins as we’re already seeing with a launch day AT&T family plan.
