Firstly, if you want to improve user experience, you need to remove autoplay videos. I agree with post above that may shock users who have max volume. And also, some people may not like your music taste
Now about payments. 20k satoshi treshold and payments to Xapo doesn't sounds very good. I think it would be better to lower treshold or remove it at all. And it would be good to allow users to choose, how to get paid. Not all people using Xapo, give them alternatives.
