For those who are on Windows 10, The lack of a native Google Play Music app means, for some, you are limited from listening to the music from your PC. Some version of Windows 10 won’t allow you to install non-Windows Store apps so that rules out Chrome for your browser and easier Play Music playing.
Enter GPMDP. The app is developed by Samuel Attard and gives you a customizable app that allows you to play your Play Music natively within Windows 10. While it is not an official Google app, it gets the job done and works really well.
