As Google Play Music has shut down, this repo will be archived as Radiant Player no longer functions. For alternatives that support YouTube Music, consider projects like GPMDP.
If anyone is interested in developing Radiant Player further, please contact @jacobwgillespie or any previous mantainer.
Radiant Player for Google Play Music™ 
Turn Google Play Music into a separate, beautiful application that integrates with your Mac.
Developed by Sajid Anwar. Originally created by James Fator at JamesFator/GoogleMusicMac.
No affiliation with Google. Google Play is a trademark of Google Inc.
Requirements
- Mac OS X 10.8 or later
- Adobe Flash Player for Mac OS X, NPAPI version
Adobe recently changed their install to try to auto-detect your browser. If you are using Google Chrome it will automatically select the incorrect (PPAPI) version needed for Radiant Player. Select a version manually and choose the NPAPI version when prompted, or install Flash via Safari rather than Chrome or Firefox.
Development
This project uses CocoaPods to handle its dependencies, though it may be cloned
and developed without having CocoaPods installed. Just be sure to open
radiant-player-mac.xcworkspace instead of radiant-player-mac.xcodeproj in order to
correctly pull in the dependencies into Xcode.
A few JavaScript dependencies are installed via npm - to update these dependences, ensure that package.json specifies the target version and run ./scripts/update-javascript-dependencies.sh.
