List of sites with free music for films ( Creative Commons mostly )

FREE MUSIC
I decided to search interwebs for free music for free use on non-commercial/commercial use, look what i found there. 
Creative common in most of the cases means free for non commercial use. Usually the requirement is to provide the autor of the song and the title track. Public domain license allows you to freely use the music in all kinds of projects. I refer to the license information for the details.
