Fred,
Thank you very much for your answer - that is the way that seemed to make most sense to me. I was only curious as to how it all functioned, and to be honest I like it that way too!
I am getting a new HD soon so I may try it out with that cumulative idea.
But for the time being, I think I will adopt your approach to it - the oldies in the Washington folder etc...
I was playing last night and thoroughly enjoying the comedy shows on NBC - they are dated now (obviously) but it gives a great insight into the mindset of the times and I found some of them really funny!
I have always been a big fan of 1940's music, so to have access to such a lot is fantastic. It is really very generous of you to provide so much great listening for free - and it must have taken ages to compile and set up the radio shows the way you have. You are to be highly commended sir!
All the best,
Stu.
