* Distinctive enough to be considered original. This means that the title must be unique and not merely descriptive of the song's content. For example, the title "I Love You" would not be considered original, but the title "Strawberry Fields Forever" would be.
* Used in a creative way. This means that the title must be more than just a simple statement of fact. For example, the title "The Beatles" would not be considered creative, but the title "HELP!" would be.
If a song title meets these requirements, it can be copyrighted and the copyright owner will have the exclusive right to use the title in connection with the song. This means that no one else can use the title without the copyright owner's permission.
However, it is important to note that copyright protection for song titles is limited. Copyright owners cannot prevent others from using the same title for a different song or for a non-musical work. For example, the copyright owner of the song "Imagine" cannot prevent someone from writing a book called "Imagine" or from making a movie called "Imagine."
