I just recently subscribed to itunes match. I had 4500 songs in my library and it only uploaded 3500. I can kind of figure out the 1k difference through the 'icloud status' column, but a few of them I don't understand. There is a whole group that says 'waiting'. Does anyone know what it is waiting for? Then there is the group, 'not eligible'. Is this because some sort of rights? Thanks!
