Use Any Music Player To Play Google Play Music Stored On Cloud!
GMusicFS is really an amazing and extremely helpful app that exposes all the cloud music available only via Google Play Music app and lets you play it on almost any third party music player for Android. App works only on rooted devices and on devices running JellyBean and above.
App might cause problems on some custom kernels (reboots).
