Startup Idea: Real-time Online Radio Listener Tracking Software

Startup idea to design a software that tracks concurrent listener gains/losses for online radio. It should provide sophisticated tracking of when and where these alterations occur based on IP tracking, and analyze trends based on time of day or during certain tracks.

I work in the online radio industry, software to track concurrent listener loss/addition in more sophisticated ways, such as during certain tracks/times of the day, when those gains/losses happen and where they're coming from based on IP tracking could be cool.
