Wix users can upload songs, images, text and SWF files.
The nature of the content users choose to upload to their website is their responsibility.
Like any other website in the world, a website created through Wix is subject to international law.
Keep in mind that if you use content/creations of any kind, you will need to consult the copyright owner first and get their approval.
