If i upload one of my own compositions as an Attribution-only license and someone else claims that they wrote the work, how can i prove that i wrote it? Is uploading the piece to enough proof in a court of law? Thanks.

I'm not sure. However, I would urge you to register your work with the copyright office in your country in all cases; such registering is considered absolute evidence of authorship. I do not know of any other method that has such certainty. --Feldmahler 12:29, 8 October 2007 (EDT)
