Answering more of your Google Site Questions 

Thank you! Yes I agree they could make the site more appealing to people who want to use it for other purposes. There is so much potential with this platform, that google hasn’t considered. Especially from a none educational users perspective. 😊

Hii... I want my site to have songs that automatically play, how do I do that?

To transfer ownership of google sites, could you share site with external user and then they can make a copy of site instead? Or you as the user can send it to a gmail account and then share it! That’s similar to what I did.
