I finally figured out why a few of my songs were tagged as "ineligible" in my iTunes library even though they were encoded at 128 Kbps (not 96Kbps or less). When I was checking the info on one of the ineligible songs, I noticed that it had been added to iTunes under an older Apple ID of mine. I checked another ineligible song and sure enough, that one had been added under an even earlier Apple ID of mine. I'm sure Apple thinks they've caught me trying to load stolen music, and my guess is that it hasn't yet occurred to them that someone would legitimately change their Apple ID as a result of an ISP being bought out (which happened to me once) or moving to a new neighborhood not served by the previous ISP (which also happened to me once). Has anyone had any success in getting this corrected?
