My wife has collected more than a few Christmas albums. I have stored most all of them in digital by now and last I looked, there were 48:45 in total. That caused me to look at the list for repeats. There were some. So, I set it as a playlist and deleted the duplicates that I could actually find. that cut the playing time down to a little less than 45 hours. This is without "Songs of the Season".
That is a lot.
