Google Music is not very efficient running as a tab in Safari. It gets lost.
Turn Google Play Music into a separate, beautiful application that integrates with your Mac. Requires Mac OS X 10.9 or above, and Adobe Flash Player.
So I decided to put something together in Fluid and tweak the CSS a bit to make it less Google and more about the music. So first off this is your desired result. It lets you enjoy the nice full moving artwork eye candy too: To start, you want a copy of Fluid, which you can buy here: You're going to need the Userstyles, so yes, you will have to shell out $5, but it's totally worth it.
Next you want an icon for your new app, I'm just using the one from the Android app itself which you can right click and save from here: Afterwards, you'll want to open up Fluid and actually create the app with these settings.
