There can be multiple values for some of these tags. For example, MPD may return multiple lines with a performer tag. A tag value is a UTF-8 string.
The response to lsinfo and similar commands may contain song tags and other metadata, specifically:
duration: the duration of the song in seconds; may contain a fractional part.
Time: like duration, but as integer value. This is deprecated and is only here for compatibility with older clients. Do not use.
Range: if this is a queue item referring only to a portion of the song file, then this attribute contains the time range in the form START-END or START- (open ended); both START and END are time stamps within the song in seconds (may contain a fractional part). Example: 60-120 plays only the second minute; “180 skips the first three minutes.
Format: the audio format of the song (or an approximation to a format supported by MPD and the decoder plugin being used). When playing this file, the audio value in the status response should be the same.
Last-Modified: the time stamp of the last modification of the underlying file in ISO 8601 format. Example: “2008-09-28T20:04:57Z”
added 13: the time stamp when the file was added in ISO 8601. A negative value means that this is unknown/unavailable. Example: “2023-11-25T13:25:07Z”
