I was thinking about subscribing to iTunes Match since Apple seems to have deprecated manual syncing of iTunes libraries to iPhones/iPods. My library consists entirely of lossless tracks (some of which I know won't match because they're high-res downloads) with heavily massaged metatdata and high-res artwork. I've read many complaints about ITM altering artwork and/or metadata (or worse, altering the track itself) in the user's library. Is this still a problem and if so can I protect my library from alteration, or should I give up on using ITM?
