This is not how copyright law works. You cannot reuse other people's copyrighted performance unless your work counts as a parody and the standards for parody are well documented. For example, Weird Al Yankovich needs to get permission for most of his parody songs because most of them don't actually qualify as parody under the law. Some do, but not all. Musical covers are generally done with permission from the rights holder. https://www.legalzoom.com/articles/posting-cover-songs-on-youtube-what-you-need-to-know https://www.legalzoom.com/articles/posting-cover-songs-on-yo... Also, the question as to whether any of the songs in question meets with the minimal creativity threshold to qualify for a copyright is a different question as to whether choreography can be copyrighted. The later is definitely the case, but the former is an open question that will answered in these court cases.
