FieldTypeReq.OpenS.Details
valuestringYesYesThe actual text of this line
startnumberNoYesThe start time of the lyrics, relative to the start time of the track, in milliseconds. If this is not part of synced lyrics, start must be omitted
endnumberNoYesThe exact end time on the same timeline as start, in milliseconds. When present, start must also be present and end must be greater than or equal to start. Only returned by songLyrics version 2 with enhanced=true

end is optional independently for each line. Its omission means the exact end is unknown. Clients may infer a fallback end, for example from the next line’s start, but should not treat it as exact source timing. Gaps and overlapping lines are valid, as is end == start for an instantaneous marker. Unsynced lyrics must omit both start and end.
