There's a large number of artists who's CDs I've bought because I was able to listen to their entire album on Grooveshark. Artists who's radio songs didn't come close to demonstrating their true skills. Of course, I've also passed on CDs because I was able to find out an artist only has 1 or 2 songs worth listening to. This is seriously going to hinder my discovering of new music. I didn't even know they were in court but I knew it couldn't last.
