Hopefully the mellow Garage Band loop on the website wasn't too offensive ;)

No, but your page still makes me play "hunt the noisy tab", and then, if I decide I want to watch the video, requires me to pause my own music to listen to your loop.

I don't object to all audio. Click-to-play and relevant? Great! But auto-playing, un-mutable, and completely unrelated is a terrible combination.

Not offensive, but annoying when you have multiple tabs open and you don't know which one the music is coming from ;)

I hope it isn't inappropriate to post this here: I've built a Chrome extension that could help you find it. http://www.mutetab.com/

Unfortunately, the current version requires that you have the extension prior to opening the tab that plays sound. (But it is fixed in my developer builds and will be available in the next version.)

I had the same problem. I opened up multiple stories from Hacker News and had to click through each of the tabs find out where the music was coming from. Perhaps you could use some sort of javascript mouse event to detect actual user interaction with the opened tab before you start playing the music loop, and yes please make it clearer in your UI on how I can make it stop.

Overall, pretty cool concept/app.

Music is gone :)
