How Radio DJs and Curators Shape What You Love
Updated
There's a moment in music listening that's hard to explain: a song comes on and you're not sure you like it, then a few minutes later you're sure that you do. The track didn't change. Something in the way it arrived — what came before it, what the programme had been building toward — made you ready to receive it.
Good radio curation does this quietly and constantly. It doesn't just select music. It creates the conditions for music to land.
What a Music Director Actually Does
Behind most radio stations — certainly behind the good ones — is someone making systematic editorial decisions about what gets played. In traditional broadcast radio this role is often called a music director or programme director. In internet radio, particularly at smaller stations, it might be the station founder themselves, or a small team with a shared sensibility.
The work is more compositional than people expect. A music director isn't just approving a list of tracks. They're thinking about:
Format and identity. What is this station? What does it sound like at 7am versus 11pm? What genres, tempos, and moods belong, and which don't? The station's identity is the sum of these decisions, made consistently over time.
The arc of a session. Good programming has shape. A morning programme might move from calm and instrumental toward more energetic as the hour progresses. A late-night set might move in the opposite direction. Individual tracks are chosen not only for their own qualities but for what they do to the sequence they're placed in.
Pacing and variety. The best programming avoids monotony. A jazz station playing forty-five minutes of upbeat swing will exhaust the ear. A slower, quieter track — even if less immediately pleasing — gives somewhere to rest, making the return to energy feel earned.
Introducing the unfamiliar. A music director who only plays what listeners already know is providing comfort, not curation. The job requires betting on something the audience hasn't encountered yet, trusting that context will make unfamiliar music legible.
The Context Problem
The same song sounds different at different times, preceded by different music. This is not a metaphor — it's how auditory processing works. The brain's interpretation of a piece of music is partly a product of what it has just heard: the harmonic expectations set by the preceding track, the emotional state produced by what came before.
A skilled curator understands this intuitively. Putting a certain track after a certain other track creates an experience neither would produce alone. The sequence is the editorial product, not the individual selection.
Algorithms can approximate sequence. They optimise for transitions that don't jar — which is different from sequencing that creates an arc, that decides a listener is ready for something more challenging than they'd have chosen themselves.
The editorial bet — "I think you're ready for this now" — requires a model of the listener's state that goes beyond their listening history. That's a distinctly human judgment.
The Long Game: Taste Formation
Radio curation isn't only selecting from existing taste. At its best, it participates in the formation of taste.
The music you love now is not the music you were born loving. It was introduced to you, at some point, by someone who made it accessible — a friend, a film, or a radio programme that played something you'd never heard before and made it feel right.
A radio station also carries authority — the implicit assertion that this music is worth broadcasting. That endorsement lowers the resistance of an unfamiliar listener. This is especially true for genres with steep learning curves: jazz, classical, and world music each require a certain amount of listening before they become fully intelligible. A good station that specialises in one of these genres acts as a patient teacher, playing accessible material alongside more demanding work, gradually expanding what feels listenable.
Many people who count jazz or classical among their primary listening habits trace the beginning of that relationship to a specific broadcast moment where something clicked.
The Internet Radio Shift
Traditional broadcast radio was geographically constrained. The editorial choices available to you were a product of where you happened to live.
Internet radio changes this structurally. The stations and collections available to explore represent editorial sensibilities from around the world — music directors whose decisions are shaped by local culture, regional heritage, and scene knowledge that would never have reached a global audience in the broadcast era.
A jazz station from Tokyo brings Japanese curatorial instincts to a global audience. A station dedicated to Brazilian music carries cultural intelligence about that scene that no international algorithm will replicate. Exploring radio by country is an encounter with entirely different curatorial traditions — one of the less-discussed gifts of the internet radio era.
Curation as Relationship
There's a reason certain radio stations acquire loyal audiences. The relationship goes beyond individual track approval — it's trust that whoever is making the decisions has taste worth following, and that following it will expand rather than narrow your musical world.
That trust is built by consistency. A station that surprises you pleasantly once is interesting. One that does it over months becomes something you rely on. You stop auditing every track and start listening in a more open, receptive state — which is when music tends to hit hardest.
The themed collections on 72FM operate on this principle: each collection is an editorial statement that these stations belong together, serve a particular listening moment, and share a sensibility. The 72FM Mixes carry the same idea, though only as far as a tag can: Deep Focus, Jazz Club, Late Night R&B, Classical Mornings, and others — each with a distinct identity and point of view, made by people.
That's the thing worth understanding about great radio curation: it's not a technology. It's a decision, made by someone who cares about music, that you should hear this.
Summary
A great radio curator does something that's easy to overlook when it's working well: they make the conditions in which good music can land. The track, the sequence, the arc of a session, the steady accumulation of context — these are the tools, and the result, over time, is a listener whose taste has actually expanded.
That expansion is different from the algorithmic experience of having your existing taste accurately mapped and extended. It's the discovery of music you weren't looking for, presented by someone who believed you were ready for it.
That belief — that editorial bet — is what separates curation from recommendation. It's why the best radio stations still feel, after all this time, like they know you better than they should.
