What are the highest ranked listened to internet radio stations in the Houston Texas area? -

Looking in to advertising with one company that states our ad would run on their internet radio stations and go out to anybody listening to one of their stations in our specific zip code area. I don t know if there are any neilson ratings for internet radio stations or not or even if this company is worth spending money on in the first place.In any event, I need to find out if there is a way to discover the most popular and highest ranked internet listened to radio stations.

How do you find this out? By bandwidth?
