In the Musixmatch API documentation it is said
Get an album from our database: name, release_date, release_type, cover art.
In the JSON response example there is also "album_coverart_100x100", but when I'm making an API call, in the response there is no image availible.
You can get an album art field as the response of album.get, but not from track.search. So if you're trying to show the album art for a result that the user has searched for, you might want to make another api call to album.get and get the value of the key album_coverart_100x100 for the url of the album art.
