To prepare for iTunes Match I ripped some old CDs. To save time I ripped two CDs at a time simultaneously into iTunes. It turns out that many of tracks ripped simultaneously have occasional drops. I would like to wait and see what matches and only re-rip the rest so I won't have to touch all of it. I don't want to upload the poor quality tracks that don't match and instead re-rip them. At that point they can upload. Thx.
