A cover song is a new version of an existing song, performed by a different artist than the original creator. Cover songs can vary in style, arrangement, and interpretation, allowing artists to put their unique spin on the music. They often pay tribute to the original artist or introduce the song to a new audience. Cover songs are common in many music genres, including rock, pop, and country. Some famous examples include Whitney Houston's rendition of "I Will Always Love You" and Jimi Hendrix's version of "All Along the Watchtower." These performances can lead to renewed interest in the original songs and artists.
