Discord.py song queuing system

I am trying to code a discord music bot and it worked until i converted the queuing system from a list of URLs to a dictionary with the song name so i can display what's playing next.

When the second song is about to play I get this error message:

C:\Users\sammy\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\player.py:611: RuntimeWarning: coroutine 'Command.__call__' was never awaited
  self.after(error)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

Here is the code, I've trimmed it a bit so that it's not super long:

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


from discord.utils import get
global voice
global queue_list
queue_list = {}

def queue():
    global queue_list
    print("hi")
    print(len(queue_list))
    if len(queue_list) != 0:
        keys = list(queue_list.keys())
        values = list(queue_list.values())
        print("AAAAAAAAAAAAA: " + str(values[0]))
        play_url(str(values[0]))
        print("AAAAAAAAAAAAA2: " + str(queue_list[keys[0]]))

        del queue_list[keys[0]]

        print(str(queue_list))

def play_url(url):
    try:
        os.remove("song.mp3")
    except:pass

    url = str(url)
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([url])
    for file in os.listdir("./"):
        if file.endswith(".mp3"):
            os.rename(file, "song.mp3")
    voice.play(discord.FFmpegPCMAudio("song.mp3"), after=lambda e: queue())

C:\Users\sammy\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\player.py:611: RuntimeWarning: coroutine 'Command.call' was never awaited self.after(error) RuntimeWarning: Enable tracemalloc to get the object allocation traceback

As your error code states you forgot to add "await" at the beginning of line 611.

C:\Users\sammy\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\player.py is the file path for your script

:611: is the line within aforementioned file

RuntimeWarning: coroutine 'Command.call' was never awaited self.after(error) is what went wrong within the file.

I hope this breakdown has been helpful for you and aids your ventures.

(Usually) means you forgot to use await before a coroutine (functions starting with async) somewhere, which is mandatory.
