A "Theme Song" is a piece of music specifically composed to represent a particular show, movie, or character. It often plays during the opening or closing credits and helps set the tone for the audience. Theme songs can be instrumental or include lyrics that reflect the themes or emotions of the associated media. These songs are important for creating a memorable identity for the TV show, movie, or character. Iconic examples include the Friends theme song, "I'll Be There for You," and the James Bond theme, both of which enhance the viewer's experience and connection to the content.
