Selecting a shared library starts connecting and gets to what looks to be 50% of the time circle and stops without connecting to the shared library..... Has anyone experience this before and knows how to overcome it?

I have an iphone 5 with the current operating system and an up to date itunes as of 01.04.13. The strange thing about this problem is that I have the "remote" app also installed and the Iphone can access the shared library and control what is played on itunes on the PC but not the other way around. What I want to do is play from my library through my Iphone but it is not connecting through the music application???
