i dont think you have anythign to be afraid of…all the free mp3’s on amazon are indie music, trying to spread their music…if amazon did somethign like spread spyware, i could see business goin down, so i doubt they’d do something that stupid.
i know you can do funky stuff with mp3’s, but i dont think i’ve ever had spyware on an mp3 before, not to say that it isn’t possible.
