Do you need legal music for your Videos?

Many musicians choose to release their songs under Creative Commons licenses, which give you the legal right to do things like use their music in your videos.

What is Creative Commons?
Creative Commons is a new system, built upon current copyright law, that allows you to legally use “some rights reserved” music, movies, images, and other content — all for free. CC offers free copyright licenses that anyone can use (without a lawyer) to mark their creative work with the freedoms they want it to carry. For instance, a musician would use a Creative Commons license to allow people to legally share her songs online, make copies for friends, or even use them in videos or other compositions.
