yikes!
I guess that's what happens when you order too many iTunes songs..
But alas I won't do this with quite a few albums, which I bought and only rarely listen. I may just run requiem on them to make them DRM free. The 256Kb higher quality items I'll get for my most listened albums, whenever the iTunes store is fully updated.. since I have 2759 "protected AAC" items in my library.. the above is just half of it..
