I see this thread just ended without a resolution, but my question is along the same lines. The user guide says:
"Songs imported from the Media Library will always be transcoded into the format m4a with 256kBit. This conversion could degrade the audio quality slightly. If you want to retain the highest possible quality for your songs, please import them as files."
What is the difference between importing from the media library, or importing them as "files"? Aren't those files in my Media library? And where would I find the songs as files instead? Or would I have to copy all those songs in the Media Library to my computer? Would that make them "files"? This is very confusing.
