Anyone who primarily uses #YouTube for just listening to music (like I do) should consider trying out an app like @newpipe (NewPipe). I haven't dealt with an ad or interstitial break since I switched, and the mobile app plays sound while my phone is locked without missing a beat. I don't know if it'll be around forever, but I do know I'm never going back to just "www dot youtube dot com" for online videos again.
Edit: Android DL link for those who want to try NewPipe: https://newpipe.net/#download

Welcome to our big, weird Magic family; I'm glad you're here! A *lot* of people have been unhappy with the price points for the upcoming Commander Masters release. I just want to reassure you that you absolutely do not have to buy any of that product to enjoy the game - especially Commander, which began as, and still primarily is, a casual-play format. I'm running out of space but I want to encourage you to not give up! Most of us don't spend a ton (all at once) on the game.
