Problematic Research

I'm trying to find the analytics on artist's I'm similar to, but I don't know what service offers that. I need to cater my music to my demo and through certain things like Repost Exchange, a new thing called Tuneden, but those are all for traction basically. How do I find the demographics and analytics of other artists or better yet an in depth analysis on their listeners? The likelihood of this getting a responses is totally slim (Jim).
