Introduction
Songs still become hits through repetition. What has changed is where that repetition comes from. For most of the twentieth century, radio stations created familiarity by playing the same tracks repeatedly across days and weeks. In the streaming era, the same psychological process remains powerful, but it is delivered through playlists, autoplay, recommendation systems and personal libraries rather than through a broadcaster’s schedule.
This shift helps explain why songs can now feel instantly familiar even when listeners cannot remember hearing them on radio. A track may appear in a workout playlist, then reappear in a personalised mix, then surface again through autoplay after an album ends. Each exposure is small, but together they create recognition. Streaming has not eliminated repetition as a hit-making tool; it has distributed repetition across many listening environments. Research on music recommendation systems and listening behaviour consistently finds that familiarity strongly influences preference and that repeated exposure remains central to how listeners adopt new music.

Why Repeated Exposure Still Drives Hit-Making
The basic mechanism behind musical familiarity is older than streaming. Psychologists call it the “mere exposure effect”: people often develop greater liking for something simply because they encounter it repeatedly. Music appears particularly susceptible to this effect because songs are designed to withstand multiple listens. Research using streaming data has found that interest in newly discovered songs often rises during the first several exposures before eventually levelling off, producing a pattern consistent with decades of psychological research. [arXiv]arxiv.orgarXivDiscovery Dynamics: Leveraging Repeated Exposure for User and Music CharacterizationOctober 28, 2022…
This matters because familiarity is not merely a side effect of popularity. It is one of the engines that creates popularity. Studies of music choice have found that familiarity is a strong predictor of what listeners choose to play, sometimes outperforming factors that people claim matter more, such as novelty.

In the radio era, programmers deliberately relied on this principle. Heavy rotation ensured that listeners heard the same songs often enough for recognition to become preference. Streaming platforms may market themselves as discovery tools, but their recommendation systems face the same challenge: introducing enough novelty to keep users engaged while maintaining enough familiarity to keep them comfortable. Spotify researchers have explicitly described recommendation as a balancing act between familiarity and discovery.

How Playlists and Autoplay Spread the Same Track Quietly
The most important change is that repetition no longer arrives from a single source. Instead, it is scattered across many listening contexts.
A listener might encounter the same song through:

- A user-created playlist shared through social media.
- Their own saved library.
Each appearance may seem independent, but together they create cumulative exposure. A song does not need a dominant radio campaign if streaming systems keep finding new opportunities to place it in front of the same listener.
Spotify’s own artist data shows how important these programmed environments have become. More than half of new artist discoveries on the platform come from programmed playlists, while a substantial share comes specifically from mixes, radio features and autoplay. [Spotify for Artists]artists.spotify.comfor Artists Spotify PlaylistsSpotify for ArtistsSpotify Playlists - Fan StudyIn fact, more than half of new artist discoveries on Spotify happen in programmed playlis…
Autoplay is particularly significant because it extends listening sessions beyond the listener’s original choice. When a playlist or album ends, the platform automatically serves similar tracks so the music continues uninterrupted. Spotify describes autoplay as a system that automatically plays related songs after a listener reaches the end of a selection. [Spotify]artists.spotify.comfor Artists Spotify PlaylistsSpotify for ArtistsSpotify Playlists - Fan StudyIn fact, more than half of new artist discoveries on Spotify happen in programmed playlis…
The result is a subtle form of repetition. Listeners may not consciously choose a track multiple times. Instead, recommendation systems repeatedly place it in their path. Some users have even complained that autoplay surfaces the same songs over and over again, illustrating how recommendation systems can reinforce familiarity through recurring selections.

The New Familiarity Loop
Streaming creates a feedback cycle that differs from traditional promotion.
A radio listener might hear a song several times a day because a station programmer placed it in heavy rotation. A streaming listener may hear the same song across multiple products because recommendation systems detect that it performs well, generates engagement or fits common listening patterns.
The cycle often works like this:
- A song gains an initial audience.
- It performs well in playlists or recommendations.
- Algorithms interpret those signals as evidence of listener satisfaction.
- The song receives more placement opportunities.

- Familiarity increases the likelihood of additional plays.
Research into music recommender systems increasingly treats familiarity as a measurable variable because repeated listening is such a common behaviour. Studies using large streaming datasets show that recency, frequency of exposure and existing familiarity are all strong predictors of future listening choices.

This helps explain why many streaming hits seem to emerge gradually rather than exploding through a single promotional event. Familiarity accumulates through repeated encounters spread across weeks or months.
How Streaming Repetition Differs from Radio Rotation
Although both systems depend on repetition, the experience feels different.
Radio repeated songs publicly
Radio repetition was visible. Everyone listening to the same station heard largely the same rotation. Hit songs became cultural reference points because millions of people encountered them together.
Programmers also worked with relatively fixed schedules. If a song entered heavy rotation, listeners could often predict they would hear it again later in the day.
Streaming repeats songs privately
Streaming repetition is personalised. Two listeners may both hear a song repeatedly, but through entirely different pathways.
One person might receive it in a gym playlist. Another might encounter it through indie recommendations. A third might hear it via autoplay after related artists. The repetition exists, but it is distributed across personalised systems rather than concentrated in a public broadcast schedule. Spotify’s “algotorial” approach—combining human editorial choices with machine-driven personalisation—illustrates this hybrid model. [Spotify Engineering]engineering.atspotify.comhumans machines a look behind spotifys algotorial playlistsSpotify EngineeringHumans + Machines: A Look Behind the Playlists Powered by…27 Apr 2023 — Personalized Editorial Playlists has been e…
The consequence is that familiarity can develop without widespread awareness that repetition is occurring. Listeners may feel they “keep running into” a song without recognising that recommendation systems are creating those encounters.
Why Familiarity Matters More Than Discovery Alone
Streaming platforms often present themselves as engines of discovery, yet research consistently shows that listeners gravitate towards familiar music. Recommendation systems therefore face a tension: people say they want new music, but their behaviour frequently rewards familiar material. [ResearchGate]researchgate.netWe show that although consumers say they would prefer to listen to unfamiliar music.Read more…
This is why recommendation systems rarely maximise novelty. Instead, they tend to introduce new tracks alongside songs, artists and sounds that already feel known. Spotify researchers have described recommendation design as an effort to balance discovery, similarity and familiarity because users generally respond poorly to either extreme. [Spotify Research]research.atspotify.comSpotify ResearchAlgorithmic Balancing of Familiarity, Similarity, & Discovery in…5 Nov 2021 — We propose a multi-level ordered-weighte…
In practical terms, playlists often function less as discovery engines than as familiarity-building machines. A track may begin as something unfamiliar, but repeated appearances across playlists, radio features and autoplay gradually move it into the listener’s comfort zone. Once that transition happens, voluntary listening becomes more likely.
That process mirrors what radio once achieved through heavy rotation. The mechanism has survived the technological shift. What changed is that repetition is now personalised, distributed and largely invisible. Instead of hearing the same song because a station plays it every afternoon, listeners hear it because dozens of streaming systems quietly place it in front of them until it feels like part of their musical world.
