Even in the US I can legally share my own pictures
Or my friend's songs that he made himself
Or all the files from the Internet Archive
Or all the Creative Commons files
Or the files from www.magnetmix.com
Or all the other public domain files
Or many more

The RIAA, CRIA, MPAA, BSA, and all the other copyright cartels, do NOT control filesharing around the world (though they would be happy if you think so).

If you are in the US, time to visit http://www.eff.org/share/
