Ok, let's clarify something:

When you create an original piece of anything, you have a copyright. Whether it's provable is the legal question and that's why copyrights are recorded with the US Patent Office and the Library of Congress.

In MySpace, you don't need to have an actual filed copyright. What they mean is that the work your posting is yours, not a cover or anything else where someone has a better claim to that song than you do. Savvy?
