Im looking to clear up a bit of space on my hard drive till I get a bigger one. There's a fair amount of stuff I don't listen to much. If I select the folders I want to burn in the iTunes Music folder and burn them to disc will all the tags and embedded artwork be preserved? If it is, am I right in thinking that when I have more space I just need to copy the files from Blu-ray back to hard drive and add them in iTunes again and artwork, tags should all be there as before?
