A compilation album is a music collection that features tracks from various artists, often centered around a specific theme, genre, or time period. These albums can include previously released songs, rare tracks, or new recordings, making them appealing to both casual listeners and dedicated fans. Compilation albums are commonly used to showcase a particular music scene, celebrate anniversaries, or promote a charity. They can also serve as a way for record labels to introduce new artists alongside established ones, providing a platform for diverse musical styles and collaborations.
