Discord 音乐机器人，为什么队列不起作用？

Question

我曾尝试在我的代码中为歌曲排队，虽然一次只播放一首歌曲，但它并没有真正起作用 我怎么能解决这个问题？ It only plays the second song in that case

async function play(connection, message){
        var server = servers[message.guild.id];
        //youtube search down
        async function searchYouTubeAsync(args) {
            var video = await youtube.searchVideos(args.toString().replace(/,/g,' '));
            console.log(video.url);
            let x = new Discord.MessageEmbed()
            .setAuthor(`? Started Playing:`)
            .setDescription(`[${video.title}](${video.url})`)
                .addField('Duration:', video.length)
                .addField('Requested by:', message.author)
                .setThumbnail(video.thumbnail)
                .setColor(7419530);
            message.channel.send(x)
            return String(video.url);
        }
        //youtube search up
        var server = servers[message.guild.id];
        const stream = ytdl((await searchYouTubeAsync(args)).toString(), { filter: 'audioonly' })
        
        server.dispatcher = connection.play(stream);
        
        server.queue.shift();

        server.dispatcher.on("finish", function(){
            
            if(server.queue[0]){   
                
                play(connection, message);
            }else {
                connection.disconnect();
                message.channel.send("**Queue Ended, left the VC**✅")
            }
        })
    
    }
    if(!args[0]){
        message.channel.send("**Error: Please provide the name/url of the song**❎")
        return;
    }
    if(!message.member.voice.channel){
        message.channel.send("**Error: You must be in a voice channel**❎")
        return;
    }
    if(!servers[message.guild.id]) servers[message.guild.id] = {
        queue: []
    }
    var server = servers[message.guild.id];
    
    server.queue.push(args[0]);

    if(!message.guild.voiceConnection) message.member.voice.channel.join().then(function(connection){
        play(connection, message);
    })  

我曾尝试将 server.queue[0] 放在 const 流中，但它并没有真正起作用。
