Well the RIAA is apperently tryin' to prosecute downloaders n charge them with the amount of money downloaded n stalled on their computers.
There have also been created so called 'screechers' planted as common mp3 files between all the regular files, if u download a file u download bits of different users, if u might happen to download a piece of a 'screecher' your file will be filled with screechy, high pitched tones through out ur download(song)..
Which makes it quite useless..
