Reply To: Creative Commons License
Copyright information is not a “license” in the sense of “little piece of paper”, so you will only need more than one if you are using different permissions for different songs. Jonathan’s solution is one sentence on his download page: “Songs that I wrote are licensed Creative Commons by-nc“. Usually the license description links to the official CC explanation so people who don’t know what it means can go look it up.
As a rule of thumb, anywhere you would stick a “Copyright, all rights reserved” notice is where you will mention CC. Since “all rights reserved” is the default for creative works, you should probably prominently state the CC license somewhere on your website, and potentially anywhere that people might encounter/purchase/download your work if you want people to make use of the freedom you are giving them.
