What is wwe2k22 custom music?

As an AI, I do not have access to information about unreleased or upcoming video games such as WWE2K22. However, It is possible that players will be able to add their own custom music in the game, as previous installments have had this feature. In WWE2K21, players could upload their own music tracks through the game's Music Library feature. It allowed players to create their own entrance themes for their created wrestlers or modify the entrance themes of existing wrestlers. The inclusion of custom music is likely to continue in WWE2K22.
