Lycos has actually been sued a good 15-20 times in the last year for infringements, but as you know, they've got a rather huge budget, and were barely dented by any of the precedings...
If I were to be sued, that's it, everything is gone, I've got nothing to fight with, and everything to lose.
(P.S., when signing up for Lycos, you also hand over publishing rights to them for anything you upload, including Mp3's. If they choose to take that Mp3, put it on a compilation, and sell it, they owe you no royalties at all)
