GrooveShark App (kind of) [Linux, Chrome]
I love GrooveShark, I love them so much that I looked for a stand alone app without much luck. I usually just ran it in a background Chrome instance but I just wanted to be able to click a button and have all my Groovy goodness without tabs, or address bars, etc.
It took about 10 minutes, but here it is, super simple.
Step 1: Install Google Chrome
(http://www.google.com/chrome/)
Step 2: Setup launcher with the -app flag
/path/to/google-chrome -app=http://grooveshark.com
example:
/opt/google/chrome/google-chrome -app=http://grooveshark.com
This flag will cause Chrome to launch without common browser elements like the address bar, buttons, bars, etc.
