Technically, there are ways to change or process music to make it more difficult to identify as an original work. These techniques include audio pitch shifting, speed adjustment, remixing, sampling, and re-arranging. However, this practice often involves copyright infringement and is not legally permitted. Please note that the use of copyrighted music without permission may not only lead to legal liability, but also damage the rights of the creator. Therefore, it is recommended to always follow relevant laws and regulations when using music and obtain necessary licenses and authorizations. If you need to use music, consider using works in the public domain or purchasing copyright licenses.
