I get those random nonsense letters whenever I defrag my iPods (I have two such devices- a shuffle and a nano), but I mostly ignore them, because my iPod nano will tell me what I have on it. The only problem I have is that the songs I get from LW don't automatically go to my iPod, so I have to manually import the songs from the My Music folder on my computer. Other than that, I can listen to any song that I have on LW on my iPod.
