Play videos and songs on the website via mpv-handler
Thanks, it used to be "_self" with iframe until some sites broke it.

And using _self in the current page will break the functionality of the site. When you return to this page, the experience is terrible.
Very nice. I would suggest that buttonPlay.target be set to _self instead of _blank so that it won't needlessly open a new window.
