It's all in the rules and regulations. In the past, because of the way the rules are laid out, we have found college band recordings of our stand tunes for them to use, because if they used our recording, we'd have go through Tresona. Songs we have found include the Horse, the Hey Song, Pretty Fly for a White Guy. Then, you just have to show the receipt from Apple Music or Amazon, or wherever you purchased the song.
there's instruction for every situation they could have.
