Discord.py Why doesn't the bot play long music from youtube?

Question

YouTube

Here is the code to play music from youtube! The problem is that the bot launches short clips with music perfectly, but if you say to play a long clip that lasts more than 10 minutes, then the bot just downloads it but does not play it.

@client.command()
    async def play(ctx, url : str):
        global voice
        channel = ctx.message.author.voice.channel
        voice = get(client.voice_clients, guild = ctx.guild)

        if voice and voice.is_connected():
            await voice.move_to(channel)
        else:
            voice = await channel.connect()
            await ctx.send(f'Бот присоединился к каналу: {channel}')
        song_there = os.path.isfile('song.mp3')

        try:
            if song_there:
                os.remove('song.mp3')
                print('[log] Старый файл удалён')

        except PermissionError:
            print('[log] Не удалось удалить страый файл')

        await ctx.send('Пожалуйста ожидайте: 5 - 10 сек')

        voice = get(client.voice_clients, guild = ctx.guild)

        ydl_opts = {
            'format' : 'bestaudio/best',
            'postprocessors' : [{
                'key' : 'FFmpegExtractAudio',
                'preferredcodec' : 'mp3',
                'preferredquality' : '192'
            }],
        }

        with youtube_dl.YoutubeDL(ydl_opts) as ydl:
            print('[log] Загружаю музыку')
            ydl.download([url])

        for file in os.listdir('./'):
            if file.endswith('.mp3'):
                name = file
                print(f'[log] Переменовываю файл: {file}')
                os.rename(file, 'song.mp3')

        voice.play(discord.FFmpegPCMAudio('song.mp3'), after = lambda e: print(f'[log] {name}, музыка закончила своё проигрывание'))
        voice.sourse.volume = 0.07

        song_name = name.rsplit('-', 2)
        await ctx.send(f'Сейчас проигрывает музыка: {song[0]}')

It's not that he does not reproduce them, but downloads for a long time. I advise you to use Lavalink.jar for the music bot
