var trackElements = document.querySelectorAll(".audio");

        continue;
    }
    var url = input.value.split("?").shift();
    var name = title.textContent.trim();
    var names = name.split("–");
    for(var j = 0; j < names.length; ++j)
        names[j] = names[j].trim();
    name = names.join("-");
    tracks.push({name: name, url: url});
}
 
var text = "";

    text += "'" + ((i + 1) + "@" + tracks[i].url + "@" + tracks[i].name.replace(/'/g, "").replace(/@/g, "[AT]")) + "'\n";


// Then in devtools, evaluate "copy(text)" in js console
