Discord Streaming: Multiple Application share [Background music]

Hello:

I recently read a post from one of your team that suggests the ability to share both your application (or screen) AND background music from another source was intentionally, or unavoidably left out. 

I'd like to request that this feature be included.

I would love to be able to share my game activity as well as my Spotify playlist (or indeed, personal music library).    I realize that allowing ALL AUDIO to play simultaneously would cause an unpleasant viewing experience, as discord itself; specifically my friends chatting with me, would be recreated on my stream. 

I'm wondering if it's possible to layer the streaming of precisely 2 applications at once.   Ie. Streaming World of Warcraft, and Spotify, but nothing more.  This would allow my game and my music to be shared, without other PC sounds interfering with the experience. 

Thank you for your time in reading my humble request.

Mr.Eso
