Where the data comes from
We listen to stations that publish the song information sent alongside their broadcasts — the same kind of metadata your radio app shows. What stations send can be messy, so we clean and verify it before counting it. A station appears once its song data is reliable, which is why the map of countries is lopsided: it reflects who publishes metadata, not who broadcasts.
How the charts are built
A song’s spins are the number of times stations played it inside the chart window, counted from the log itself. The wider figures answer different questions: how many stations played it, and how many countries those stations sit in. Airplay is not sales and not streams — a song high in these charts is one radio programmers are choosing to play, which usually moves slower than a streaming chart.
The playlists
Some pages include an unofficial playlist associated with a station’s reported airplay. The playlists are not made by the stations, and station names identify whose airplay is being reported. Any embedded player belongs to the music service, and following a playlist takes you there.
What this site is not
We host no audio. The player plays a station’s own stream, where that stream allows it. We are not affiliated with any station or with Spotify, and trademarks belong to their owners. We correct the messy text stations broadcast, but we publish what was actually aired, including the station slogans and spoken tags that repeat every hour, which we keep out of the charts but not out of a station’s own log.
Quoting and removing a station
The logs are facts, and you are welcome to quote them with a link back to the page they came from. If you run a station that does not want to appear here, write to us and we will remove it. To ask for a station to be added, use the form on the home page. Most requests are settled within a few minutes.
