Still trying to organize/learn this software but.... I have about 500? CDs and sure I can import all of them into my iTune music on my Mac, but that would take up a lot of space. I can save them on to an external storage but for this purpose, when importing music for the first time into your Mac, Do you click or unclick "Copy files to iTunes Media folder when adding to library" on preferences ? Also, on import settings, do you normally use "MP3 Encorder" or "Apple Lossless Encodoer" \recommendation ? What about Greatest Hit Album under ONE band or artist ? It often get mixed up on an album that has multiple artists in it if it has guest players in the album, then some get thrown out of the song list, or automatically goes to "completion" category instead of one artist greatest hit album.... how do I fix this ?
