What are the steps to adding music to your shows?

I have been using Talkshoe for a little while now and I am so confused and frustrated because I am trying to figure out a simple easy cheap way to have music added to my shows and play intros and so on. I have asked questions and gotten answers that mean nothing to me because I do not understand them. I need a step by step explanation on how to do this, what programs i need to download if any, and anything else that will help me. Please someone come to my aid! This website is really good, but awful with explanations and figuring out how to use it. I would appreciate some good solid answers. Thank You.
