Upload a soundtrack
If you want to upload a soundtrack into your classes, this quick tip video shows you how to do it.
Note, you must use an mp3 file, and you need the rights to use it commercially. That's one we recommend sites like Pond5.com and Melodyloops.com, since the pricing is so attractive ($10 is not out of the question) and the rights enable you to use the soundtrack for many, many classes.
