Honestly, the site or app as they call it is a total mess. You use a song in a video, they get your all day's labour destroyed by muting the audio. Tell me how on earth will your video get to your audience without the sound. They will tell you, you don't have the right to use the sound, even when the sound is gotten from the video editor you're using. These sounds are free for everyone. Please remove this hindrance. Cause with this alone, I can't give it any star.
