What is a compilation album?

A compilation album is a collection of recordings from various artists or bands, typically released by a record label. These albums can be themed around a specific genre, era, or artist. They can feature popular tracks, previously unreleased songs, and rare or live performances. Compilation albums are often used to introduce new artists or to showcase the highlights of a particular period or style of music. They are also popular among music fans who want to discover new music without having to purchase multiple albums from different artists. Some of the most well-known compilation albums include "Now That's What I Call Music!" and "The Essential (Artist)".
