Music can be a critical component of your trailer. And while everyone wants to use their favorite artists and songs, we do have to keep in mind the rules governing copyright. With a little searching, you can most likely discover a good but royalty free tune to use. And, yes! You have to cite your sources!
Something to keep in mind about music is that you will need to have the actual music file (mp3) saved in your folder in order to upload it to MovieMaker or Animoto. It cannot be a link or streaming music.
If your song is from a CD or iTunes or Amazon, your citation will look like this:
Artist (last name, first). "Title of Song." Name of album, copyright date. MP3 file.
Example:
Jones, Norah. "Light as a Feather." The Fall. Blue Note Records, 2009. MP3 file.
If your song is from a website like Jamendo, your citation will look like this:
Artist (Last name, first). Name of song. Recording date. Recording Company. Name of website. Web. date (day month year). <website url.>
Example:
Beethoven, [Ludwig van]. Egmont Overture, op. 84. Cond. Willem Mengelberg. Rec. 14 Jan. 1930. Victor. n.d. Internet Archive. Web. 24 Dec. 2009. <http://www.archive.org/details/BeethovenEgmontOverturemengelberg>.
