The Artist’s Guide to Radio Tracking Terms: Spins, Adds, Rotation, and Reports

Radio has its own language, and it can make new artists feel like outsiders at their own party. Radio spins, radio adds, rotation, dayparts, impressions — these airplay terms get thrown around in pitches, charts, and reports as if everyone was born knowing them. Nobody was. Here is the working vocabulary, defined in plain English.

The Basics: Spins, Adds, and Rotation

Spin

One complete play of your song on a station. Spins are the atomic unit of airplay — every chart, report, and rotation decision is built on counting them. “How many spins did we get this week?” is the first question of every radio campaign.

Add

A station’s formal decision to place your song into its scheduled rotation. An add is bigger than a single spin: it is a commitment to keep playing the record. When promoters brag about “adds at twelve stations,” this is what they mean.

Rotation

The scheduling system that determines how often each song on a station’s playlist gets played. Songs are grouped into tiers — typically light, medium, and heavy — and your tier decides your weekly spin count at that station.

Light, Medium, and Heavy Rotation

Programming guides generally describe light rotation as roughly one spin a day — on the order of five to ten plays per week — often used for newer or developing records. Medium rotation means a steady presence with multiple plays per day. Heavy rotation is the top tier: the songs a station plays most, many times daily. Moving from light to heavy multiplies your airplay without adding a single new station.

Recurrent

A song that has passed its peak as a current hit but stays on the playlist at reduced frequency. Graduating to recurrent is not a failure — it means the record had a real run.

Timing: Dayparts and Drive Time

Daypart

A block of the broadcast day. Nielsen Audio, the main U.S. radio audience measurement service, divides the weekday into five dayparts: morning drive (6–10 a.m.), midday (10 a.m.–3 p.m.), afternoon drive (3–7 p.m.), evening (7 p.m.–midnight), and overnight (midnight–6 a.m.).

Drive Time

The commute windows — morning and afternoon drive — when listening peaks. A spin at 8 a.m. reaches far more ears than the same spin at 3 a.m., which is why when you are played matters almost as much as how often. Overnight-only spins are real, but programmers read them as a test, not an endorsement.

Geography and Audience: Markets, Reach, and Impressions

Market

A station’s metro listening area, such as Atlanta or Dallas–Fort Worth. Airplay spread across many markets signals that a record travels — five spins in five markets often tells a stronger story than twenty-five in one.

Reach

The number of different people who hear a station (or your song) over a given period. Two stations can spin you equally while delivering very different reach.

Audience Impressions

Spins weighted by audience size — one spin on a big-market station counts for more impressions than one on a small station. Several major industry airplay charts rank songs by audience impressions rather than raw spin counts, which is why a record with fewer spins on bigger stations can outrank one with more spins on smaller ones.

Proof and Identity: Reports, Metadata, and ISRC

Airplay Report

A document summarizing your airplay over a period: total spins, the stations that played you, and where. A professional report — like the PDF airplay reports SpinCounts generates, with spin totals, station lists, and a geographic heat map of your strongest markets — is the standard proof you hand to labels, promoters, booking agents, and grant or showcase applications.

Metadata

The text data attached to your recording: artist name, track title, featured credits, and codes. Airplay tracking works by matching what stations broadcast against music-catalog metadata, so inconsistent metadata can leave your spins miscredited or uncounted.

ISRC

The International Standard Recording Code — a unique identifier assigned to each recording, usually by your distributor. It is how the industry tells your version of a song apart from every other recording, which makes it central to accurate airplay matching and royalty payment.

Charts: Position, Movement, and the Tracking Week

Chart Position

Your rank on a chart for one week, based on accumulated airplay. Genre charts rank you within your format — your actual competitive lane — while all-genre charts rank you against radio as a whole.

Tracking Week

The fixed window over which a chart counts plays. Industry airplay charts are typically tallied over a set week — Billboard’s country airplay chart, for instance, counts Monday through Sunday — and weekly charts reset the race every seven days.

Chart Movement

Your change in position week over week. Movement is often more persuasive than position: a record climbing 38–25 signals momentum that programmers and press respond to.

Put the Vocabulary to Work

Knowing the airplay terms is step one; watching them happen to your own music is the fun part. SpinCounts tracks verified spins in real time across 1,400+ online and FM stations and turns them into charts and reports you can actually use. Claim your free artist profile or sign up free — and the next time someone says you are “getting medium rotation in three markets,” you will know exactly how good that news is. Real airplay. Verified spins. No guessing.
