title: Discord.py rewrite and youtube_dl
body: <p>I've been trying to create a discord bot for my server and I'm stuck on a problem.
  How can I play music using youtube_dl without having to download it? Right now I'm using:</p>
  
  <pre><code>with youtube_dl.YoutubeDL(ydl_opts) as ydl:
  ydl.download([url])
  </code></pre>
  
  <p>It downloads the song, and then I play it. It works, but it takes around 15 seconds to do all of that, which isn't bad, but I was wondering if there was any way to make it faster? For example, Rythm Bot is instantaneous.</p>
  
  <p>Thanks in advance for any help given.</p>
