Have you ever heard of wizard rock? Here's the Harry Potter Fandom wikipedia definition:
"Wizard rock is a musical movement dating from 2002 that consists of a number of bands formed by young musicians playing songs about J.K. Rowling's Harry Potter literary phenomenon. The lyrics are usually humorous and simple, and many bands write songs from the point of view of a particular character in the books, usually the character who features in the band's name.3 If they are performing live, they may also cosplay that character. Though most fans of the music are previous fans of Harry Potter, some bands have attracted listeners outside of the Harry Potter fanbase. Wizard rock has recently evolved to become deeper and more refined.
Harry and the Potters was the first wizard rock band but inspired other wizard rock bands."
