Industrious One has created Musicality for Mac (http://getmusicality.com/). The $11 app is designed to “break your music out of the browser” and offer desktop conveniences like keyboard shortcuts, AirPlay streaming, and more to over a dozen of the world’s most popular music services.
With it, you can play, pause, skip and rate songs on any supported music service. Musicality for Mac supports 15 music services to 15.
Musicality requires Mac OS X 10.10 or newer and an Internet connection. It may be downloaded as a free 10-day trial from the Musicality website. The demo is full-featured and unlocks in-place when purchased.
