So I came back from a few days away and found that iTunes match had gone live where I am (Switzerland), so went to the mini that has the fullest version of my library and activated match, then let it get on with its thing. I came back after it was done, and everything was fine. I then turned on match on my other computers/iOS devices and all seems well. I am, however left with a few questions that perhaps the good folks here can answer. 1) how do I find out whether a particular song is matched or just uploaded (or a list of the matched songs and a list of the uploaded ones) 2) for matched songs, how do I upgrade them from whatever lower bit-rate version they are currently at up to 256k? 3) if I go to the iCloud pane in System Preferences, it says my iCloud storage is still almost entirely empty, yet when I was matching a bunch of songs definitely were uploaded (I have a few obscure songs in there and a few recordings of songs that I made with friends that are definitely unmatchable, so they must have been uploaded). What gives?
