So, I plopped my money down for iCloud music match and I can't listen to much of my music on my Mac. Specifically: (1) I can select a song from iTunes on my Mac and it will play; but (2) I can't play the entire album. These song are all in a faded font on my computer. I'm assuming it means they are in the "cloud" somewhere but I'm at a loss as to how they come back to my computer. Help.
