While I agree with the sentiment, in this case all I can say is: You're missing out. I enjoyed the relaxing, ambient-ish sounds combined with tempting links to Wikipedia articles.

I'm not sure there is a good solution to auto-playing. People are fine with it on well-known sites like YouTube, Vimeo, Soundcloud, etc. And most people, when they unwittingly click on a YouTube link, blame the person who made the link, not the site itself. Bizarrely, the target of ire shifts to the site if it's not popular enough.
