So I just got a new 256 gb retina mbp and am having a little confusion with the audio storage. I just transferred my old itunes library over via external HD and I have ~30.5 GB (6500 songs) worth of material. Now, I checked my overall storage on my computer and it says I have over 117 GB of audio taking up space right now... How is that possible and how do I fix it? Im a little concerned given that I got this comp a week ago and I already only have like 100 gb of storage left.
