Hi, A few years ago, I used iTunes to rip all my CDs (about 1000 disks, 10'000 tracks) to Apple Lossless in .m4a files. Now I keep hearing that iTunes does not have very good error correction, and so some of my rips may not have been that good. So my question is if I can retrospectively use your Accurate Rip database to check if those rips were Ok or not? I definitely do not want to insert all the 1000 CDs in the drives, so my question is if Accurate Rip can compare the contents of my existing ALAC .m4a files against the Accurate Rip database? Ideally in a batch process.
