Music controls for SAO Launcher.
To use the app, start playing music (With Google Music, for example). Then use SAO to pause/play and skip/rewind songs.
The app uses in app purchases because paid apps are encrypted (and thus do not work as extensions). Don't worry, your purchase will be remembered even if you uninstall or get a new phone. If not, email us (xlythe@gmail.com) and we'll help out.
