Imagine this scenario:
You spend ages rating all your songs using the star rating.
You invite some 'mates' round and run eJukebox in kiosk mode.
After a few drinks your mates decide it would be funny as hell to set everything at 5 stars....

This hasn't happened to me yet but I can see it happening in the future, could you mabey lock the star ratings when in kiosk mode (i.e. not allow people to change them).

Your mates have too much spare time on their hands. I guess it is quite limited how much damage they can do unless they take shifts by clicking through your entire collection.

But you might be on to something, it leads me to another suggestion, which might be more complex, though... when in kiosk mode, eJ is normally installed at either parties, in pubs or similar... how about that it would register each additional star rating, and divide the sum of ratings by the number of times the song is rated - to put it simples, give an average rating?

So if Bob decides to give a 5 star or a 1 star rating, and the song allready has a 3 star rating, it would end up as a 4 star or a 2 star, until the next time the song is played and someone gives it a new rating. Add a time interval of one hour, or per session or something, so someone cannot mess it up by clicking back and forth between the stars.
