They provide a perfect entry point for new listeners who want to explore an artist's work without navigating a deep discography.

A standard greatest hits album is defined by commercial success and popular acclaim. The core tracks are usually singles that achieved high Billboard Hot 100 positions, significant radio airplay, or strong sales. However, the tracklist often includes beloved album tracks ("fan favorites") and, crucially, one to four new or previously unreleased songs. These new tracks serve as a powerful incentive for devoted fans who already own the original albums, transforming the compilation from a "best of" for casual listeners into essential new material for the faithful.

Many of the songs featured on these albums are "classic and timeless wonders," notes a 2021 Facebook post, which often become the basis for modern music, being frequently sampled and interpolated.

However, one thing remains certain: In a sea of infinite choice, being told "these are the best songs" is a relief. The algorithm can guess, but a greatest hits album is a statement of consensus. It says: "The world agreed these were great."
