I am a new Mac user and wanted to start ripping my cds and create a high quality library of backups. I have been using XLD and have been ripping two sets of files, FLAC and mp3 (for iTunes). I wanted to check older rips I have from when I used Easy CD-DA on a Windows machine in the AccurateRip database. Anytime I "open folder as a disk" in XLD I get a message, "This CD was not found in the CDDB". Can someone point me in the right direction? Also, I have some rips that I have not saved cue sheets. Are they important and should I re-rip those again and start saving cue sheets from now on? Any help or advise would be great!
