Last.fm API發送2首歌曲，如果我正在收聽當前正在收聽的歌曲

使用user.getRecentTracks，Last.fm會發送2首歌曲，儘管我設置的限制爲1.由於某個聰明人，如果我目前沒有收聽曲目，則只發送一首曲目。Last.fm API發送2首歌曲，如果我正在收聽當前正在收聽的歌曲

例如：http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&user=yeppaul&api_key=b25b959554ed76058ac220b7b2e0a026&limit=1

這裏是我的jQuery：

$(document).ready(function(){ 
    $.ajax({ 
     type: "GET", 
     url: "http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&user=yeppaul&api_key=61d9a12fccfc085e5ddc70beccdbeaae&limit=5", 
     dataType: "xml", 
     success: showListens 
    }); 
}); 

function showListens(xml) { 
    $(xml).find("track").each(function() 
    { 
     $(".listen").append("<a href=" + $(this).find("url").text() + ">" + $(this).find("artist").text() + " &mdash; " + $(this).find("name").text() + "</a><br /><br />");  
    }); 
}
