如何让我的音乐机器人播放有限的歌曲播放列表？

Question

在我的音乐机器人上进一步发展......我试图从让他播放一首歌曲然后离开，到让他播放有限的歌曲列表然后离开。

这不应该与队列混淆 - 歌曲列表是预先确定的和有限的。 它不能被机器人添加或更改，至少目前是这样。 不过，该机器人确实对列表进行了洗牌。

现在的问题是，不是一首一首地播放列表中的歌曲——他播放第一首歌曲，然后是第二首……然后就停止了。

我尝试根据 SongToPlay 数组的长度设置一个循环，但所做的只是让机器人在每首歌曲中快速发送垃圾邮件（在前一首歌曲有时间播放之前），然后离开。

const connection = message.member.voice.channel.name;
            const channel = message.member.voice.channel;
            message.channel.send("Now playing Scythe OST in the "+connection+" channel.");
            var SongToPlay = shuffle(testbells);
            channel.join().then(connection => {
                console.log('Now playing '+SongToPlay[0]+'.');
                message.channel.send('Now playing '+SongToPlay[0]+'.');
                const dispatcher = connection.play('./Scythe Digital Edition - Soundtrack/'+SongToPlay[0]+'.mp3');
                dispatcher.setVolume(0.1);
                dispatcher.on("finish", () => {
                    SongToPlay.shift();
                    console.log('Now playing '+SongToPlay[0]+'.');
                    message.channel.send('Now playing '+SongToPlay[0]+'.');
                    connection.play('./Scythe Digital Edition - Soundtrack/'+SongToPlay[0]+'.mp3');
                    dispatcher.setVolume(0.1);
                });
                channel.leave();
            })
            .catch(console.error);

const connection = message.member.voice.channel.name; const channel = message.member.voice.channel; message.channel.send("Now playing Scythe OST in the "+connection+" channel.");

var SongToPlay = shuffle(testbells); channel.join().then(connection => {
    let currentSong = 0;
    const keepPlaying = () => {
        console.log(`Now playing ${SongToPlay[currentSong]}.`);
        message.channel.send(`Now playing ${SongToPlay[currentSong]}.`);
        const dispatcher =
        connection.play(`./Scythe Digital Edition - Soundtrack/${SongToPlay[currentSong]}.mp3`);
        dispatcher.setVolume(0.1);
        dispatcher.on("finish", () => {
            if (currentSong < SongToPlay.length - 1) {
                currentSong++;
                keepPlaying();
            }

        });
    }
    keepPlaying();
}).catch(console.error);
