Just a warning to those that want to replace all their old music with iTunes Match files. I had my old library very organized and had every song with the proper artwork IMBEDDED in the mp3 files. Since I replaced all my files with new 256kbps AAC files they are now missing a lot of artwork. Apple doesn't imbed artwork (they link artwork). For some reason (I can't really tell you why) I prefer to have the artwork imbedded. Over the next few months I'll go through and imbed all the artwork. I've already done my A's so there's a start.
