The things that I learn via MR. "Empty Data." Who would have thought?Chundles said:No, they're a special type of compression called "empty data." You know how all data is just ones and zeros and the computer knows how to interpret those to make it into something useful right? Well, empty data means that all those ones and zeros are there, they're just outlines of ones and zeros instead of solid characters. Because of all the space in there they can be compressed right down to almost nothing. When Apple grants you a song, it sends the selected song an order to start filling in the outlines - almost like colouring in a stencil - and the song begins to appear.
P.S. Thanks for the chuckle!
