A Creative Commons license allows you to keep your copyright and to invite others to share your work. By releasing your songs with a CC license, you make it clear what your listeners can and cannot do with your music.
There are so many great reasons to publish your music with a CC license:
It's free promotion and marketing.
You keep the rights to your songs.

Each of your song profiles will contain a CC icon that listeners can click to find out more about how you've chosen to release your song.

To find out more about Creative Commons in general and the ways their licenses benefit musicians and their fans, we strongly recommend that you take a look at all the resources available on the Creative Commons website: http://creativecommons.org/ And, for a more thorough examination of the relationship between creativity, innovation and the law, you can take a gander at Lawrence Lessig's book, The Future of Ideas
Moreover, Creative Commons is an international licensing agreement—which means it's an even more powerful way to protect your rights than copyright. Share your music under a creative commons license.
