Among the best streaming music services you'll find on BlackBerry 10
Slacker is a hugely popular on-demand music service for BlackBerry 10 and other platforms, and their app is fantastic.
Though the UI follows closely in the standard Cascades layout, it has a very distinctive style in and of itself. Users can flip through stations in the catalog, mark them as favorites, and have what you’re listening to shared out to Facebook. There are over 200 stations available, including more talk and news-style ones from ABC and ESPN.
You can listen for free, so long as you’re willing to get through the occasional audio ad, or you can pay $3.99/month for unlimited skipping, no ads, and offline caching, or go big with Premium to get all that and music on demand for $9.99.
