It will be just a quickie. Looks like there are no official builds made for Centos to use Spotify and Discord. Either you have to download *.deb packages(Ubuntu and Mint users quite happy there) to "alienate" them.. or use the source provided. I tried to use Discord from the source but was tired to dig into dependency issues. It's always that libffmpeg.so or another lib.soffmpeg. (I have a bad love/hate relationship with FFmpeg in general on Linux)

Luckily, there is an amazing script who saves a day!

I recommend installing Canary, as it works for sure. And Spotify you can get from negativo repository here:

Spotify client

But looks like there won't be updates in the future. Or at least for a while.
