Google Play Music Desktop Player offers a level of customization that is simply not available in the web player. You can customize your theme, change the colors, and send your play history directly to last.fm. It even has an equalizer. This desktop player can do it all, from advanced audio controls to simple song changes notifications, It is lightweight and standalone, so it will consume far less resources than Google Play Music opened in a standard Chrome tab. This allows you to use your computer's resources for things you care about instead of playing music.
Open source means that the app is available on GitHub. This gives you the opportunity to have input into all features we create. You can also get involved and help out. We will look into it if you have a problem or suggestions.
This is a minor release of Google Play Music Desktop Player. It's been a long time coming so quick shout out to everyone for struggling on and waiting for this release.
