Responses

Different Responses given out by the API, are listed here.

If any error occurs the value of the error key will be set to true else false

"error": false //no error occured

Most of the lyrics are time synced or have timetags and some aren't time synced or have timetags. To differentiate between synced and unsynced we have key syncType.

"syncType": "LINE_SYNCED"

Musixmatch supports Line synced and Word synced type of timed lyrics. Line Synced is the timetag is given till which the line is sang and the word synced lyrics time specifed when the word comes up in the song. For now Spotify only supports line synced. Maybe they would support word synced in the future :/.

LINE Synced

{
    "error": false,
    "syncType": "LINE_SYNCED",
    "lines": [
        {
            "timeTag": "00:00.96",
            "words": "One, two, three, four"
        },
        {
            "timeTag": "00:04.02",
            "words": "Ooh-ooh, ooh-ooh-ooh"
        }
    ]
}

NOT Synced or Unsynced

Note the timeTags is set to 00:00.00.

{
    "error": false,
    "syncType": "UNSYNCED",
    "lines": [
        {
            "timeTag": "00:00.00",
            "words": "jaane nahin denge tuje"
        },
        {
            "timeTag": "00:00.00",
            "words": "chaahe tujh ko rab bulaa le, hum naa rab se darane waale"
