I am in the process of developing a new website but do not really want to re-invent the wheel if it has already been done before. So, what I am looking for, is a script that allows people to rate music, sort of like billboard's top 100. I want it to show a list of 10 or 20 songs and people can rate the songs. At the end of the week, I want to be able to tally the votes and then reassign the current position on the list. So say song 5 on the list had the most votes, it would get moved to position 1 at the end of the week. Does anyone know if anything like this exists before I go ahead and make my own?
