Spotify's feature that generates a playlist of your recently replayed songs is called On Repeat.
On Repeat is a personalized playlist built from tracks a listener has played frequently over a recent period. It is designed for songs that have become part of someone's current listening habits, rather than for brand-new recommendations. Spotify updates the playlist automatically as those habits change.
A common mix-up is Repeat Rewind, which focuses on songs a listener played heavily in the past but may no longer be playing as often. Discover Weekly, by contrast, recommends unfamiliar music based on listening patterns, while Daily Mix playlists combine familiar favorites with related tracks.
On Repeat is therefore a snapshot of a listener's current musical phase. Its contents can change as new songs receive repeated plays, making it different from a manually created favorites playlist or Spotify Wrapped's end-of-year summaries.
