I don't tend to like sound when I visit a site - but I often wonder why companies who have a branded sound or chime, don't use it (sparingly) on their website.

For example, and who I think can get away with it:

- NBC - ding, Ding, ding
- McDonald's - Bah, dah, ba, bah, bah
- Playstation - ziiuuuum

EA Sports was the only one that I found that used it when I launched the site - a familiar sound to anyone who knows their games.
