And I think iTunes does >ask you "are you sure" before you delete ? Well, K.T., it may well have done so. I don't recall. Whatever happened, it didn't forcefully enough make me sit up and realize what I might be doing as I proceeded. Yep, as part of a train of what I might call "anticipatory steps" one (at least speaking for myself) wants to get on with the immediate task at hand and never mind the "lead-ups". There's something psychologically askew here about tying so closely that irreversible deletion decision to getting on with a more immediate task (getting an MP3 made). Granted, this applies only to idiots like me. We folks need a picket fence set up to protect us from our own immediately pressing myopic concerns. Dave
