Doesn't slow down the interface at all. I wish the mobile version didn't cost to use

Until there's something wrong with this script on my end, this deserves five stars from me. It's quick and does the job. So far the adbox has no recurring load glitches, but NoScript would have a part in that anyway.

Simply put: If you want the ad gone, install it.

To fix the problem of this script edit it and replace the line "listen.grooveshark.com" with "grooveshark.com"
Simple!

No luck on Chrome for Mac. I'll change my review if this is updated. Of course, someone prove to me that it's Chrome's fault and not the script and I'll gladly remove it as well.

Does what it should, but leaves those with firebug consoles open lots of errors everytime a new ad tries to load in the hidden iframe... fixed these problems here: http://userscripts.org/scripts/show/66804

Does exactly what it says on the tin.

I'm giving you 4 stars for lame "fake updates".

It may not be the most advanced scripting in the world, but it does exactly what it promises.
Thanks for this. :)
