音乐机器人完全停止音乐，而不是跳过一首歌discord.py

Question

当我使用我的skip命令时，我的程序停止播放音乐，而不是跳过歌曲。 这是代码：

queues = {}
players = {}
opts = {
            'default_search': 'auto',
            'quiet': True,
        }
voice_states = {}

class voice:
    def __init__(self, client):
        self.client = client

    @commands.command(pass_context=True)
    async def skip(self, ctx):
        id = ctx.message.server.id
        players[id].stop()

    @commands.command(
        pass_context=True
    )
    async def play(self, ctx, url):
        server = ctx.message.server
        channel = ctx.message.author.voice.voice_channel
        try:
            await self.client.join_voice_channel(channel)
        except:
            print(" ")
        if server.id not in players or players[server.id].is_done():
            server = ctx.message.server
            voice_client = self.client.voice_client_in(server)
            player = await voice_client.create_ytdl_player(url, after=lambda: queue(server.id), ytdl_options=opts)
            players[server.id] = player
            await self.client.say('Now Playing ' )
            player.start()
        else:
            server = ctx.message.server
            voice_client = self.client.voice_client_in(server)
            player = await voice_client.create_ytdl_player(url, after=lambda: queue(server.id),  ytdl_options=opts)

            if server.id in queues:
                queues[server.id].append(player)
            else:
                queues[server.id] = [player]
            await self.client.say('Now Playing ' )
            await self.client.say('Video queued.')

    def queue(self, id):
        if queues[id] != []:
            player = queues[id].pop(0)
            players[id] = player
            player.start()

def setup(client):
    client.add_cog(voice(client))

我没有收到错误代码， 只是没有队列。 修复了我的代码或自己的解决方案。 抱歉，很长的代码，但是您需要所有上下文
