Situation: I have ripped all my CD's into iTunes, now that I'm becoming a fiend of quality, I'd like to use Apple Lossless Audio Codec (m4a) in order to use Airplay to my Pioneer receiver, and load on my iPhone for the best possible sound with no compression. My hopeful solution: I'd like to take the CD's I have, rip via FLAC then convert to an Apple Lossless file then drop it into the directory for iTunes (User/Music/iTunes/iTunes Music) and the KEEP all the data in iTunes already. Does that make sense? Within iTunes I'd like to keep all the play counts, ratings, songs in playlists right where they are, etc....the only thing I am doing is deleting the mp3 / aac file and replacing it with lossless. I really don't mind going through all my albums and doing this one album at a time, to me it's worth it. Or is there another way to go about this?
