No, sound effects are not a song.
A song is typically a musical composition consisting of lyrics (words) and melody (tune) that is intended to be sung or performed by a human voice or an instrument.
Sound effects, on the other hand, are audio recordings that are used to enhance or create a specific atmosphere or mood in a film, TV show, or video game.
While sound effects can be an important part of a music composition, they are not the same as a song itself. Sound effects can add depth, texture, and emotion to a song, but they are typically used to complement and enhance the music rather than being the main focus.
