But torrent files don't aren't in themselves illegal, even if they point to illegal content. TPB doesn't host illegal material. It only hosts the files that point to them. So technically, they're not being illegal.
That said, my thoughts are based on US copyright.
Please mod me down, but this case is a bit more complicated than "I like to torrent Music" and other self-serving interests.
The problem with this case is that TPB isn't US. Sweden laws say they're fine.
