A simple music bot written in discord.py using youtube-dl.
Though it's a simple example, music bots are complex and require much time and knowledge until they work perfectly.
Use this as an example or a base for your own bot and extend it as you want. If there are any bugs, please let me know.
Requirements:
Python 3.5+
pip install -U discord.py pynacl youtube-dl
You also need FFmpeg in your PATH environment variable or the FFmpeg.exe binary in your bot's directory on Windows.

the download links have a set expiration date which is relative to 6 hours for me
if someone plays an amount of tracks longer than 6 hours the links from the last ones will expire

i tried to fix it by doing:

                try:
                    async with timeout(180):  # 3 minutes
                        self.current = await self.songs.get()
                        newsource = await YTDLSource.create_source(self._ctx, self.current.source.url, loop=self.bot.loop, passedoptions=self.current.source.options)
                        newsource = Song(newsource)
                        self.current = newsource

and it so far has worked at renewing the links so that they don't expire

how do I import ffmpeg?

I’m pretty sure that question is answered above, but In the shell do pip install ffmpeg, and wait for that to load. If that doesn’t work, type ffmpeg in the console and a thing should pop up about installing it, do the first one and wait and it should work.

first try "pip install ffmpeg" in your terminal, then download ffmpeg-git-full.7z here https://www.gyan.dev/ffmpeg/builds/ . Finally you should extract it in a convenient location and add the bin folder to your PATH here's a quick tutorial for win10: https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/
I'm sure that there are better ways to do it but it worked for me
