this is because the content owner (UMG in this case, apparently) decides if it can be viewed on mobile devices or not. so not much i can do about that, sorry :/
I have been looking everywhere for the full original of Yoji Biomehanika - a theme from banginglobe. I just realised you have it but it's not available to mobile devices. Could you change that? It would be great if you could! Love your channel by the way :)
