What a listener is hearing right now: a record, or the station talking

Attributes (8)

Attribute	Type	Required	Description
kind	'record' | 'break'	Yes	record is music. break is the station speaking on its own between two records (an ident, a bulletin, a talk break), with artist empty and title the break's own label. A presenter talking over the start of a record is not a break: the record is what is on air, and it stays record. Absent means record, which is all a station older than this field ever reported. default: record
title	string	Yes
artist	string	Yes	Comma-joined, as a display line rather than a list: this is what a player or a device shows, not something to iterate. Empty for a break
album	string	No
artworkUrl	string	No	The station's own cached cover, as a path under the API root (art/...). Absent while the station does not yet hold the cover, which a player answers with the station's logo; never a provider's URL
durationMs	number	No
startedAt	number	Yes	Unix epoch millis, as observed when the player reported the track started
remainingMs	number	No	Absent when the decoder cannot say. It leads the listener by the encoder and client buffers, so it is a display value and not a schedule
