coroutine 'music_cog.play_next' was never awaited self.after(error) RuntimeWarning: Enable tracemalloc to get the object allocation traceback

I'm making a discord music bot that play audio from youtube without downloading, the play function from file music_cog looks like this:
async def play_next(self, ctx, path):
voice = discord.utils.get(self.client.voice_clients, guild=ctx.guild)
lst = open(path + "/list.txt", "r")
urls = lst.readlines()
lst.close()
if len(urls) > 1:
del urls[0]
lst2 = open(path + "/list.txt", "w+")
for url in urls:
lst2.write(url)
lst2.close()
url = urls[0]
player = await YTDLSource.from_url(url, loop=self.client.loop, stream = True)
if not voice.is_playing():
ctx.voice_client.play(player, after=lambda e: self.play_next(ctx, path))
asyncio.run_coroutine_threadsafe(ctx.send("No more songs in queue."))
#commands.command(hidden=True, pass_context=True)
async def yt(self, ctx):
voiceChannel = discord.utils.get(ctx.guild.voice_channels, name=ctx.message.author.voice.channel.name)
bot_channel = ctx.guild.voice_client
if bot_channel == None:
await voiceChannel.connect()
voice = discord.utils.get(self.client.voice_clients, guild=ctx.guild)
path = "C:/Users/Laptop88_LTV/Documents/GitHub/Python/Bot/music_bot/Nymphosic/music_zone/voice_channels/" + str(voiceChannel.id)
if not os.path.exists(path):
os.makedirs(path)
lst = open(path + "/list.txt", "r")
url = lst.readline()
lst.close()
# url = 'https://www.youtube.com/watch?v=D4Fi1YBbzDY'
voice = discord.utils.get(self.client.voice_clients, guild=ctx.guild)
async with ctx.typing():
player = await YTDLSource.from_url(url, loop=self.client.loop, stream = True)
if not voice.is_playing():
ctx.voice_client.play(player, after=lambda e: self.play_next(ctx, path))
await ctx.send('Now playing: {}'.format(player.title))
else:
await ctx.send("``` Already playing. ```")
However, it stops after playing the first song, the error said: C:\Users\Laptop88_LTV\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\player.py:616: RuntimeWarning: coroutine 'music_cog.play_next' was never awaited
self.after(error)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
What should I do to solve it?

Discord.py making a queue command

I am in the process of making a discord.py music bot (my first) and am wondering how to make a queue. I'm guessing that it has something to do with the asyncio command (import asyncio) but I really don't know.
from discord.ext import commands
from discord.utils import get
import asyncio
import youtube_dl
import os
bot = commands.Bot(command_prefix='>')
bot.remove_command('help')
#bot.event
async def on_ready():
await bot.change_presence(activity=discord.Activity(type=discord.ActivityType.listening, name=">help"))
print("Bot is online! Logged in as: " + bot.user.name + "\n")
#bot.command(pass_context=True)
async def ping(ctx):
await ctx.send(f'**Pong!** Latency: {round(bot.latency * 1000)}ms')
#bot.command(pass_context=True, aliases=['j'])
async def join(ctx):
channel = ctx.message.author.voice.channel
voice = get(bot.voice_clients, guild=ctx.guild)
if voice and voice.is_connected():
await voice.move_to(channel)
else:
voice = await channel.connect()
await voice.disconnect()
if voice and voice.is_connected():
await voice.move_to(channel)
else:
voice = await channel.connect()
#bot.command(pass_context=True, aliases=['l'])
async def leave(ctx):
channel = ctx.message.author.voice.channel
voice = get(bot.voice_clients, guild=ctx.guild)
if voice and voice.is_connected():
await voice.disconnect()
else:
print("Bot was told to leave voice channel, but was not in one.")
await ctx.send("OneBeat is not connected to a voice channel. Connect OneBeat to a voice channel before using this command.")
#bot.command(pass_context=True, aliases=['p'])
async def play(ctx, url: str):
channel = ctx.message.author.voice.channel
voice = get(bot.voice_clients, guild=ctx.guild)
if voice and voice.is_connected():
await voice.move_to(channel)
else:
voice = await channel.connect()
await voice.disconnect()
if voice and voice.is_connected():
await voice.move_to(channel)
else:
voice = await channel.connect()
song_there = os.path.isfile("song.mp3")
try:
if song_there:
os.remove("song.mp3")
print("Removed old song file.")
except PermissionError:
print("Trying to delete song file, but it's being played")
await ctx.send("Error: Music is already playing (Queue feature coming soon).")
return
await ctx.send("One second...")
voice = get(bot.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("Downloading audio now\n")
ydl.download([url])
for file in os.listdir("./"):
if file.endswith(".mp3"):
name = file
print(f"Renamed File: {file}\n")
os.rename(file, "song.mp3")
voice.play(discord.FFmpegPCMAudio("song.mp3"), after=lambda e: print("Song done!"))
voice.source = discord.PCMVolumeTransformer(voice.source)
voice.source.volume = 0.5
nname = name.rsplit("-", 2)
await ctx.send(f"Now playing: {nname[0]}")
print("Playing\n")
bot.run('token')

Not really! I have no idea how to use asyncio and I still managed to make queues. My way of doing it is to have a json file that contains dictionaries and lists. Which looks something like this:
{
"queueskey": [
{
"channelid": [],
"queue": [],
"status": []
},
{
"channelid": [],
"queue": [],
"status": []
},
{
"channelid": [],
"queue": [],
"status": []
}
]
}
Something like that repeating over and over again. You can also have extra info stored as well with that. Though it took me quite some time to debug and make the thing work, I'd say this is one of the simplest ways of doing it.

Need help making a discord music bot

I'm making a music bot, and, im struggling with some parts. I don't know how to make the skip part or play the next song in the queue once the current one ends. Any help?

You can get code for understanding its not the proper-one but it can help you.
Music Bot Code
You will get an idea how to code these commands.

python discord music bot youtube_dl

import discord
import youtube_dl
from discord.ext import commands
-----------------------------------------------
#cat.command(pass_context=True)
async def play(ctx):
if not ctx.message.author.voice:
await ctx.send('you are not connected to a voice channel')
return
else:
channel = ctx.message.author.voice.channel
await channel.connect()
server = ctx.message.guild
voice_channel = server.voice.client
async with ctx.typing():
player = await YTDLSource.from_url(url, loop = client.loop)
voice_channel.play(player)
await ctx.send(f'**Music:**{player.title}')
Is there any way to fix this error?
AttributeError: 'Guild' object has no attribute 'voice'

Check this working example.
import discord
import youtube_dl
from discord.ext import commands
ydl_opts = {
'format': 'bestaudio/best',
'postprocessors': [{
'key': 'FFmpegExtractAudio',
'preferredcodec': 'mp3',
'preferredquality': '192',
}],
}
def endSong(guild, path):
os.remove(path)
#cat.command(pass_context=True)
async def play(ctx, url):
if not ctx.message.author.voice:
await ctx.send('you are not connected to a voice channel')
return
else:
channel = ctx.message.author.voice.channel
voice_client = await channel.connect()
guild = ctx.message.guild
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
file = ydl.extract_info(url, download=True)
path = str(file['title']) + "-" + str(file['id'] + ".mp3")
voice_client.play(discord.FFmpegPCMAudio(path), after=lambda x: endSong(guild, path))
voice_client.source = discord.PCMVolumeTransformer(voice_client.source, 1)
await ctx.send(f'**Music: **{url}')
Optional, useful function
If you want you can make your bot leave the voice channel after the song stops playing. Add this at the end of your code:
while voice_client.is_playing():
await asyncio.sleep(1)
else:
await voice_client.disconnect()
print("Disconnected")

Try to replace if not ctx.message.author.voice: with if 'voice' not in ctx.message.author:

Discord bot does not accept commands when other command is running

I'm developing a discord bot that can find spotify playlists and queue the tracks' youtube counterparts. I have a loop running that uses a list of tracknames to search for a video on youtube, it then grabs the top result and sends to an asynchronous function that plays it. However, whilst the bot is in this loop it does not accept other commands. Can I make this run concurrently with other commands? The following is all the code of my application

I would definitely suggest using the module threading. I do not currently have enough time to read your code and put it in, though I might edit this answer later.
Refer to:
https://docs.python.org/3/library/threading.html
Threading allows you to run multiple functions at once.

You're using blocking libraries. Discord.py is a asynchronous library and you need to use things that don't block your code. In Frequently Asked Questions you can see a example using requests library, that's blocking and you should use aiohttp to make asynchronous requests instead.
