As mentioned, it's not a settings issue we can address. Back in the day, YouTube allowed people to post up videos using popular songs. Unfortunately, over the years, they've changed their rules and now block any video that have songs produced by just about every company out there (Warner, UMG, etc.) on mobile devices. Needless to say, that's the reason why you can't see them. There are ways around it and you'll have to use one of the methods outlined above. All our new videos use songs that we have bought the rights for and so you shouldn't have issues with them.
