Not sure if this is the right stack site to ask this. I have a channel for kids in a non English country. We want to make a song ourselves for a video and we need an instrumental to sing the song with. I am wondering if we are allowed to download an instrumental from one of the royalty free sites and use it for making the song. Note that the song would be used only in that one video.
Also, I saw that there are instrumentals being sold on Amazon, can we use these?
Thanks!
