Dear all, today I logged into iTunes to listen to a few of the 3.5k songs I have uploaded to iTunes Match few months ago. ... just to discover that they are still in the list but with the grey exclamation mark next to them ... Seems they can't be found anywhere. This happened to roughly 80% of my library. I know Apple had some problems concerning iTunes in these last weeks. Should it be a passing thing like "the-server-where-my-music-is-phisically-stored-is-temporarily-down"? or something more serious? Thanks all M. G.
