The video above is a quick demo by the developer. The app works by mounting your Google Play Music tracks as a FUSE filesystem — one that most Android music players will check when you scan for new music. Since the music appears to be local, your favourite player will treat the files normally and play them seamlessly. Of course, because this all requires admin-level changes, it will only work on rooted Android devices. Still, it may be a good price to pay to use your favourite player with your cloud-stored music collection.
XDA developer bubbleguuum came up with the tool and has confirmed it works with most popular players, including our favourite, PowerAmp. It also supports previously mentioned n7player and Winamp for Android. We tested it out, and it works like a charm — as long as you have a supporting device and player (and most players should work).
Hit the link below to make sure your device meets the system requirements, and to download the app — it’s completely free, and the developer is actively working on it, so expect regular updates.
