I am EXTREMELY sorry I purchased this piece of software and let it "clean" my iTunes libraary. I listen to mainly Trance and Jazz (a weird mix I know), and this thing has completely destroyed my iTunes database. I am having to go through each CD individually to fix what it messed up. It reassigned CD names to sometimes only 3 songs on the whole CD-making the CD appear in 2 different places in the library. Other times, it would add album artists to only SOME of the songs on the CD-Again orphaning some songs while leaving others where they belong. I realize this software uses CDDB/Gracenote to get its song titles. That being said, Gracenote must be in complete dissarry. I WISH I could get a refund for this piece of junk software. I do NOT recommend this software unless you have too much time on your hands and enjoy manually cleaning up what it "fixes". AVOID AT ALL COSTS!
