I screwed up my iTunes music library by rewriting the album name of ALL my albums, to the same name. Now I'm trying to undo it. I've tried various things: 1. Using the Previous iTunes Library folder to change the .itl file 2. Used a backup to rewrite the Music folder within the iTunes Media/Music folder None of these solutions worked. It seems that it keeps updating back to the corrupt library. I think it may have something to do with iTunes match but can't be certain. I've tried it various ways, turning iTunes Match off first before replacing folders and such, but when I start iTunes back up, iTunes Match is turned back on and it says it's updating my library and reverts the albums names back to the corrupt names. Has anyone had this problem before and what are some other possible solutions I can try?
