It's very convenient when you can just find and play your favorite music on YouTube. But one thing I always find restricting that in-spite of large music collection that YouTube have you can't play music while screen off or while doing multitask! That's just plain waste of all the music on YouTube.
YouTube's official app doesn't allow you to do so. But it provides background play with its new music key which is premium service that you can opt for 7.99$ ! and also its not available in all countries. I think that background playing feature should be included in official app cos it's necessity and it's should be integrated in the app without any added cost.
