So, I just finished downloading 18k tracks from iTunes as they were all matched with the iTunes store. After all is said and done, I have to wonder why would Apple give out their versions of the file (I'm assume they are superior to the tracks I had)? Sure it's nice to have all my 96-192k files replaced with their 256k versions (in which I can hear the difference between 128k and 256k), but I have to wonder what's in it for Apple?
