I have a twist type of question....I like the sounds on this site (no idea how to make them myself) and I would like to know if they can be used in a video on youtube that promotes a product. (not my own, and the music files are not being sold, just used as background music.) I promote other people's products by creating a video for it and sending them to the product creators website.
is this legal or can they not be used for that?
thanks in advance for the advice
