Guest user question.

What I am trying to do is set up a guest account for a headphone meet. I want to be able to have all of my music and a player (not iTunes) but nothing else of my system. Internet and stuff is fine but not anything from my system. Can someone point me in the direction for this? My system is a mid 2010 Macbook Pro running Yosemite.
Thanks

It sounds like you want the Shared folder in /Users. See here for more details.

Here is what Apple says about accounts, how to set them up, and how to restrict what is accessed.
