NEVER, EVER, start ,music without me pushing some button. even if it's a music site. NEVER
Honest opinion, how do you feel about http://www.pandora.com/ auto playing?
i cannot access it because i am in the uk, if i am not wrong, i hheard a couple of days ago from another thread that it's a radio right?
well i would probably feel the same. The fact is that the user usually does not expect it, therefore it might create awkward moments in the office or else, i think it's not a good thing for the website. You risk to loose an user even before he sees you homepage.
