Social media and streaming are the main background forces.
Live shows (including military performances in Korea), memes, and YouTube often act as catalysts.
As a result, fewer new songs enter top chart positions—a paradox worth examining.
Why old songs rise again on the charts
Since the mid-2020s, the music chart landscape has shifted.
As streaming became the default way people listen, reverse chart runs have become more common.
Meanwhile, organized online communities and fandom campaigns can change rankings quickly.
Together, these trends raise questions about the music ecosystem as a whole.
For example, industry data from January 2026 reported that new releases made up less than half of tracks entering key charts in the prior month.
Therefore, this is not just a passing fad but a structural change.
Consequently, we should not treat reverse runs as mere feel‑good stories.
Instead, we must consider both their benefits and their problems.
Reverse runs invert the usual flow of music discovery.
However, that inversion only happens when several conditions align.
This column moves from definitions to causes, examples, debates for and against, and finally policy implications.
Readers should expect fresh questions at each turn.
Where reverse runs come from
The idea of rediscovery is not new.
For example, in 1829 Felix Mendelssohn helped revive interest in J.S. Bach nearly 80 years after Bach's death—a historical example of reappraisal.
But the modern phenomenon of digital-era reverse runs is born from the mix of streaming platforms and social networks.
On‑demand listening (play what you want, when you want) makes it possible for an overlooked track to be found and gradually climb the ranks.
Since the mid-2000s, listening habits changed and the frequency of reverse runs rose.
In markets that once prioritized new-release promotion, older tracks now get attention in new contexts.
Video platforms in particular can make rediscovery happen very fast.
During that process, fandom actions and platform algorithms interact in decisive ways.
Why they happen
The causes are multiple.
First, the intrinsic quality and broad appeal of a song set a foundation.
Second, social media virality and mentions by influencers act as critical triggers.
Third, memes and challenges reframe songs for new audiences.
In addition, playlist placement and recommendation systems matter.
If an algorithm repeatedly surfaces a track, its stream count accumulates naturally.
Offline triggers—soldier concerts, TV broadcasts, ads—can link to online sharing and accelerate the effect.
Ultimately, only when several conditions are met does a chart rebound become real.
Concrete examples
Examples help us understand the mechanics.
Brave Girls' "Rollin'" became famous for a combination of military base performances (a Korean context where soldiers request songs), viral clips, and a highly organized fan push that steadily lifted the song up the charts.
This shows how coordinated fandom action can produce measurable chart impact.
Psy's "Gang" (often discussed for its late rediscovery) followed a different path: YouTube circulation and cover culture helped the original track reach new listeners.
Similarly, some indie songs have reappeared after being used in videos or playlists, illustrating how platforms and cultural practices spotlight older material.
Pros: what reverse runs do well
They prompt reappraisal.
First, reverse runs give well-crafted songs a second life beyond their original release window.
This reuse of cultural goods can be seen as a form of cultural recycling.
Second, fans' voluntary participation strengthens community bonds.
Organized streaming and sharing are collective acts that create shared meaning, not just individual listening.
Third, there is economic value: renewed plays generate additional royalties and licensing income, which can fund further artistic work.
Therefore, reverse runs can turn into sustained revenue, not only a short-term spike.
Fourth, there are cultural and educational benefits.
Younger listeners who encounter older songs learn music history organically.
Thus reverse runs expand listening horizons and preserve cultural memory.
Cons: concerns and downsides
Opportunities can be crowded out.
By contrast, reverse runs risk squeezing exposure for new releases and emerging artists.
If chart attention concentrates on older tracks, the incentives for labels to invest in new talent may weaken.
Second, fairness and chart credibility become issues.
Coordinated streaming by a dedicated group may distort charts that should reflect broad public taste.
Such distortions reduce discoverability for independent acts.
Third, the industry may shorten its investment horizon.
If labels chase viral returns, long-term artist development could suffer.
That would reduce stylistic diversity and risky, experimental projects.
Fourth, legal and ethical questions arise.
Organized streaming campaigns may clash with platform terms or raise concerns about manipulation.
So norms and self-regulation will be important.
Structure change and online behavior
The system itself has changed.
Modern fandoms act as prosumers (producer + consumer), not just passive listeners.
Algorithms and communities combine to refocus attention on older songs, and "push" campaigns and memes play central roles.
Fans invest time and attention on platforms.
Concentrated streaming is a kind of resource allocation—almost like a collective investment.
Therefore, the metaphor of investment helps explain why fans commit sustained effort.
In career terms, reverse runs change how creators plan.
Artists and labels now consider that older songs can generate long-term returns, which may push them to diversify revenue models.
The uncertainty resembles startup planning and risk management in other creative industries.
Finally, reverse runs are a form of cultural learning.
When older songs re-enter public attention, listeners and artists reinterpret past works, creating new points of intergenerational dialogue.
Policy and industry recommendations
Balance is needed.
Platforms and labels should consider standards to protect chart integrity, such as clearer streaming aggregation rules and ethical guidelines for organized campaigns.
At the same time, policies to increase exposure for new artists must be part of the solution.
Industry players should also reinvest in long-term artist development.
Relying solely on viral hits risks hollowing out creative diversity.
Finally, educational programs that promote music history and consumption variety can help listeners appreciate both new and old works.
Conclusion
Reverse chart runs combine cultural rediscovery with structural questions.
In short, they arise from a mix of social media, algorithmic platforms, and organized fandoms. They can rediscover great songs while also reducing opportunities for new releases.
Therefore, strengthening platform transparency and supporting emerging artists are logical starting points for a balanced response.
This column has presented causes, examples, and arguments on both sides.

Your judgment will matter in future debates about the music industry's direction.
