I wish you could have a @TeamYouTube video playing while the window is closed and be able to use other apps at the same time. I don’t need to watch it, only listen to it, and I’d like to play a game or two while I listen.
Background play feature is available with our paid YouTube Premium subscription. The music/video will continue running in the background when you leave the app. Here's more info: https://goo.gl/Twbiqv . Hope this helps.
