A compilation album is a music collection that features tracks from various artists or a single artist, often curated around a specific theme, genre, or time period. These albums can include previously released songs, remixes, or new recordings, making them a popular choice for fans who want a diverse listening experience. Compilation albums are commonly used to showcase the best works of a particular genre, such as rock, pop, or jazz, or to celebrate a specific event, like a movie soundtrack. They can also serve as a way to introduce listeners to emerging artists or to highlight the greatest hits of established musicians.
