I know you didn't ask but if someone else has a question about those files:
Those music files are for use with the Video Wave, MyDVD, and the Slide Show programs as "Smart Sounds".
Open Video Wave, add an image or video and then click to add background music. A window will open and give you an option for Smart Sound or your music. In MyDVD, select "Change Menu Audio)
This is an easy way to add background music when you don't want or need to add specific music of your own. If your project is long, you can set Smart Sound to play for the entire project and it will be hard to tell where it loops.
There is a reasonable selection of music BUT
you can buy more.
