The idea is good. But the app is still far from being really useful.

The idea is good. But the app is still far from being really useful. Many bugs, unexpected shutdowns, does not have access to a global shortcut, it would be interesting to have a preview of upcoming music … By using Rdio, the album cover does not update, but this is a bug already known to the official app Rdio. Im hoping that the developer launch new versions with new features and improvements.
