Start with one missing broadcast: the exact recording, station and local date and time.
Check the correct track version, dates and station filters. Then confirm the station’s country and feed—similar names or regional feeds can refer to different broadcasts.
Mention if the recording was a radio edit, sped up, pitched or mixed into a DJ set. These details help investigate recognition and whether the play belongs to another version.
If the station was not monitored then, older plays may not be recoverable. Use station coverage to request it; a request does not guarantee a historical backfill.
