The music available in Storykit is from Youtube's royalty free library meaning that you have full access to use all of these songs, always!
Why does this message appear?
What we can't manage over is other people using this free service, and sometimes people can claim the right to a certain song which Facebook might believe. This causes confusion when several other people use the same song and what Facebook does then is to say no to the unknown. In this case you can always "claim your right" and demand that Facebook analyze the situation.
This might take a little while but then Facebook will always come back with an okay to publish the video since you have used a 100% royalty free song open for anyone to use. If you think the wait to too long we suggest you to choose another song or just publish without sound. But remember, you always have the right to use these songs!
Problem with another country
The music can also have different rights in different countries, and what might be okay to use in Sweden might not always be as okay in another country. In this case, try another song and please report to Storykit what song this applies to so that we can remove it from our library.
