"Megastar needs the daily users and a % of these will become "active" users and engage in voting and therefore revenue."
That is not correct!
A DAU (daily active user) is already engaged in voting, interacting with performers by commenting, watches live streaming, listens to a few songs or just opens the app to check the scoreboard for a few minutes. DAU's are what MSM is after and that's what they report about. That's where the money is at!
So MSM does not need a percentage of these DAU's at all!
Maybe you were meaning MAU's? (monthly active users)
Monthly Active Users (MAU) is one of the ways to measure the success rate of online social games, social networking services and, increasingly mobile apps. Typically, metrics are measured by counting the number of unique users during a specific measurement period, such as within the previous 30 days.
