I have had to quickly exit the browser a few times when I've been on a public computer and the handbag loop suddenly blares out loud, much to the annoyance of whoever is nearby. I think you should have the cartoons play by default, but without the loop, just have the normal dialogue. I have bytesize switched off, unless I hear that there's been new ones added. As someone else said (might have been Luis?), if you feel you have to have music it should be something quiter and less sudden.

I leave it turned off, personally. It's not that I don't like the clips. It's just not what I'd go to the front page to do, so it ends up more invasive to me than accommodating.
