There are many places online where you can obtain a sample music sync license document. Docracy has a decent example here.

However, sometimes it is just easier to license music directly from platforms such as Synchedin. Artists and Creators often don’t want the hassle of having to go through contracts and email back and forth and then have to sign a legally binding agreement which in most cases they don’t understand. Synchedin will take away all that hassle and provides artists and creators with a very simple solution that helps them find the music they are after and license the track legally for use worldwide in any platform.
