Hi everybody, I hope this type question hasn't been beaten to death. However, my situation is a little different. I have just recently re-ripped all of my music into higher bit rate files onto my iMac (AND made loseless backups onto an external drive 'ugggh'). Then I have my MB, which I use more often, that has extensive list of smart playlists and playlist all of which I would like to keep. (files on my MB are the older 128 quality files) My question is, how can I export ALL of my playlists from the MB into my iMac so that my playlists will reflect all the files, just with the higher bit rate? From this point I will then re-transfer my iMac's itunes into my MB. Is this what 'File/Library/Export Library' do this? I hope somebody can help. Right now I only see two solutions. Export each playlist individually. Or, remake all my playlists .
