Here's the deal. All of my music is on my desktop, but I work from my laptop. So I have my music mapped over a network drive. Works freaking awesome. Lately, I have noticed that if I make a playlist on my laptop and then export it to my Desktop, it will sometimes (not always) add several tracks that I didn't have on the list, to begin with.
Has anyone else see this happen or am I just short bussing it here?
