When doing projects with students that require music to be added, please encourage them to use royalty free music. It may seem like a little thing, but truly there are copyright laws that prohibit students from using copyright music in their own production without the written consent of the musician. The student could always pay a licensing fee that would allow them to use the song, but the cost for something like that can be $50+. Royalty free music is music that is free to be used by anyone without restriction. http://incompetech.com/m/c/royalty-free/ is a great website for students to use when thinking about music for a project. They can sample the music and then download it. I like this website because it has a large variety of music to choose from and each musical piece has a description of the music. Check it out.
