this is 100% exactly the same script that was released by Sebastián Alegría a little earlier.

his was a "modified" older version of this script

since the script by Sebastián Alegría does work (not flawlessly at first when u start up grooveshark the "player" is the same size as it was with the ad-banner up, but that fixes itself when u switch to My Music or whatever, but indeed does what it is supposed to do)

naturally this one does work aswell

This is the best Grooveshark ad-removing script I've seen around. It works with dynamically added CSS code. Nice work.
