iTunes is horrible with metadata, and as a result, my library is messed up. There are three major problem I'm having: 1.) Songs/Albums disappearing completely: Back in the days before buying music from the iTunes Store was mainstream, I imported my entire collection of CDs (we're talking hundreds) to iTunes. I've migrated my library to several new computers since then, and now half of that music is gone with no trace. Now, I don't even have a computer with an optical drive. I might buy an external one, but I really don't want to import all of those CDs again. 2.) Album Titles/Artwork disappearing: iTunes is infamous for showing "Unknown Album" with a blank album cover on half of your library. This seems to happen randomly with no rhyme or reason, and there doesn't seem to be any obvious fix. Granted, the names of the songs are still there. However, it's inconvenient for anyone and painful for people like myself who have OCD. 3.) Split Albums/Duplicate Songs: There are way too many instances of duplicate songs in my iTunes Library and again, no easy way to alleviate the problem. A new problem that's started happening fairly recently is the same album appearing twice, each instance with only some of the songs. If anyone could help me with these issues, I'd greatly appreciate it.
