I hate any site that autoplays audio, no matter what it is. Even worse when it's something like this, though.

I'm not the guy you replied to but I didn't know what to expect when I followed the link, I had no idea what "Nyan Cat" even means.
But it's on Hacker News, so it would be something interesting and valuable, right? ;)
Yes, browser isn't for audio.
