How To Make A Song Play After Current One Ends Discord.py

I'm doing this discord bot and I'm trying to find out how to just continuously check if the song is playing and when it ends, check if there is a song in the queue, and if it is, play it if not, do nothing. I wanna know if there's like an event for when an audio ends? I have tried a while loop but that won't work.

AN EVENT FOR WHEN AUDIO STOPS PLAYING OR SOME LOOP:
    if len(queue):
        voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
        source = FFmpegPCMAudio(f"{next(next_song)}.wav")
        voice.stop()
        voice.play(source)
        await ctx.send("Next Song Playing")
        queue.remove(source)
