the purpose and character of the use, for example whether your project is for profit
the nature of the copyrighted work, for instance, if the song is a famous Billboard hit or an academic piece of music
the amount of the copyrighted work that you used in your project, and
the effect of the use upon the potential market for or value of the copyrighted work.
