A Growl-like notification system for Grooveshark
Requirements: Max OS X 10.8 or later
Safari
This code uses the notification center introduced in Mac OS X 10.8 and Safari's ability to allow webpages to interface with this. It mimics Growl's ability to discreetly show you the current song being played as it starts playing.
To use: Open a Grooveshark window in Safari and copy the line in growlshark.js into the browser bar. You might have to check "Allow JavaScript from Smart Search Field" under the Develop menu.
If an alert box appears asking for permission to use the notification center, allow it.
That's it! You will see new songs pop up in the notification center.
