in fact, you can already find music licensed via Creative Commons around the web. check out SoundCloud for example,

https://soundcloud.com/search/sounds?q=work&filter.license=to_modify_commercially

click on one of the songs returned from this search, then click on the Creative Commons license logo and you will see how the author has chosen to license the work. as an example (that I did not listen to), https://soundcloud.com/3lau/work-hard-play-hard and when you click the license link, http://creativecommons.org/licenses/by/3.0/
