Final answer:
The creator of an original song holds the copyright and must grant permission for remixes to avoid copyright infringement, which can result in legal consequences and substantial damages.
Step-by-step explanation:
Under copyright law, the creator of the original song would own the copyright for that work, which includes the exclusive rights to reproduce, distribute, and display the song. However, this ownership does not automatically extend to all the remixes that others may create. People who wish to remix a song generally need to seek permission from the copyright holder and may need to pay for a license to use the original song in their new creation. Without permission, creating a remix could be considered a case of copyright infringement, which can lead to costly legal battles and substantial damages, as highlighted by the case where Marvin Gaye's family won over 5 million dollars from singers Pharrell Williams and Robin Thicke for plagiarism.
