The UE4 Twitch broadcasts are mostly talking heads, making them perfect for just listening to. It would be great to get an audio only version as well at the time the latest installment is posted to Youtube.
There are plenty of websites that would give you mp3 version of any youtube video for free, not sure if it’s ok to post some here, but just do a search and you’ll find them in no time. There are also extensions for various browsers that’ll do the same thing.
