Without knowing: All money goes into the same pot and gets divided per what's listened to totally. There's no point in doing it per user.

Take Shinkansen for example, http://en.wikipedia.org/wiki/S... "Between Tokyo and Osaka, the two largest metropolises in Japan, up to thirteen trains per hour with sixteen cars each (1,323-seat capacity) run in each direction with a minimum headway of three minutes between trains." That's over 50,000 people per hour so why does 50,000 per day seem unlikely?
