A music cover is a new version of a song originally performed by another artist. In a cover, the new artist interprets the song in their own style, which can include changes in arrangement, instrumentation, or vocal delivery. Covers can be found across various genres and are often used to pay tribute to the original artist or to introduce the song to a new audience. Many artists, including Taylor Swift and John Mayer, have gained popularity by creating covers of well-known songs. Covers can be released as singles, included in albums, or performed live. They allow musicians to showcase their creativity while honoring the original work.
